Bell-and-pad enuresis training and dry-bed training

1. Introduction

Version followed: two procedures are covered. (a) Bell-and-pad (urine alarm) conditioning: the Mowrer and Mowrer (1938) principle, run to current practice standards from the International Children's Continence Society (ICCS) standardization document (Nevéus et al., 2020) and NICE CG111 (2010), with overlearning as ICCS and the alarm literature describe it. (b) Dry-bed training (DBT): Azrin, Sneed and Foxx's three-stage programme for children (1974; first developed for adults with intellectual disability in 1973), as Bollard (1982) operationalises it. Houts' Full Spectrum Home Training (FSHT) is a later alarm-based package; its components are named where relevant, but its manual is not drawn on [uncertain].

What it is. Both are home-based behavioural treatments for nocturnal enuresis. The family runs them over weeks, and a clinician assesses, sets up, coaches and reviews. Bell-and-pad uses a moisture sensor, either a pad under the sheet or a body-worn sensor in the underwear. When urine reaches the sensor it sets off an alarm (sound or vibration). The child wakes, stops voiding, finishes in the toilet and resets the device. DBT keeps the alarm and adds an intensive first training night, positive practice, cleanliness training, a graduated waking schedule and social reinforcement. [source: Bollard 1982; NICE CG111 ch. 12; Nevéus et al. 2020]

How change happens. Mowrer's account is classical conditioning. The alarm (unconditioned stimulus) produces waking and inhibits voiding. Bladder distension is repeatedly paired with it and becomes a conditioned cue, so the child either wakes to void or holds on through the night. Lovibond later proposed an avoidance account, in which the child learns to avoid the aversive alarm. Both accounts give the same practical rule: the alarm must lead to full waking at the moment wetting begins, every night. DBT adds operant learning: correct night toileting is rehearsed and praised, and wetting is followed by effortful corrective routines (Azrin's "negative consequence"). [source: Bollard 1982; Azrin, Sneed & Foxx 1973 abstract]

Current standing (important before you start). ICCS and NICE recommend the alarm as first-line treatment for children whose family is motivated. NICE's guidance for families advises against dry-bed-type packages, meaning programmes that combine rewards, punishments, training routines, waking routines and alarms. It also advises against any training that involves holding on, delaying urination or stopping the flow. ICCS calls routine scheduled waking neither medically motivated nor curative. DBT is therefore described in full below for completeness and fidelity. Where it conflicts with current guidance this is flagged, and you should regard it as a second-line or specialist option, not a default [source: NICE CG111 IFP 'General advice'; Nevéus et al. 2020]. Note also: the Society of Clinical Child & Adolescent Psychology (effectivechildtherapy.org) rates alarm and DBT as 'works well' and retention control training as 'tested and does not work'. Sources disagree on DBT [uncertain].

2. Framework

Who it is for. Children aged about 5 and over with nocturnal enuresis, after medical assessment. ICCS: alarm suits frequent wetting with a motivated child and family. It is less suitable for infrequent wetting, parental sleep problems, a shared bedroom, or several wets a night. NICE: offer an alarm when advice on fluids, toileting and rewards has not worked. Do not offer it when wetting is very infrequent (under 1–2 wet nights a week), when parents are struggling emotionally, or when they express anger, negativity or blame towards the child. For children under 7, consider it according to the child's maturity, motivation and understanding. Daytime symptoms or secondary enuresis do not exclude an alarm. [source: Nevéus et al. 2020; NICE CG111 as summarised by GPnotebook]

Format. Delivered at home by the family. The clinician runs an assessment and set-up appointment (child and parents together, with a device demonstration), makes a check-in call at 1–3 weeks, holds reviews at about 4–6 weeks and about 3 months, and supports any relapse. In original DBT, a trainer (Azrin's research staff) supervised the first night in the home. Later variants taught it in the office [source: Bollard 1982; Azrin, Hontos & Besalel-Azrin 1979, uncertain].

Bell-and-pad: phases

Phase	Goal	Typical duration	Move on when
0. Assessment and preparation	Rule out medical causes; treat constipation and daytime symptoms first; baseline diary; check family suitability	1–2 visits plus 1–2 weeks of diary	Monosymptomatic picture or co-problems treated; family motivated and not blaming
1. Set-up and teaching	Device demonstrated; child rehearses alarm routine; records and rewards agreed	1 session	Child can do the routine by daytime rehearsal
2. Active alarm training	Alarm every night without breaks; parent wakes child immediately	ICCS: judge at 6 weeks. NICE: review at 4 weeks, reassess at 3 months. Average course is often several months	Progress (smaller wet patches, fewer wets, waking to alarm, some dry nights) → continue. No progress at 4 weeks (NICE) or 6 weeks (ICCS) → stop or switch
3. Success criterion	14 consecutive dry nights	n/a	Reached → stop the alarm, or go to overlearning
4. Overlearning (optional; recommended after relapse)	Extra evening fluid while alarm continues	Until 14 consecutive dry nights again	Achieved → stop alarm; follow up
5. Follow-up and relapse	Monitor; retreat promptly if relapse	Months	Relapse → repeat a course (often shorter) or add desmopressin via the prescriber

[source: Nevéus et al. 2020; NICE CG111; GPnotebook 'Alarms in bedwetting'; Bollard 1982] The ICCS 6-week and NICE 4-week review points differ. A review at 4 weeks with a decision by 6 weeks satisfies both [synthesis].

Dry-bed training: stages (Azrin et al. 1974 via Bollard 1982)

Stage	Content	Duration	Move on when
1. Intensive training night	Pre-bed explanation, extra fluids, 20 positive-practice trials, hourly wakings with toilet trips and praise, cleanliness training plus positive practice after any wet; alarm on	One night (trainer-supervised originally)	Next evening → Stage 2
2. Post-training supervision	Alarm on; one parental waking, first set at about 3 h after bedtime and moved 30 min earlier after each dry night; stops when it falls within 1 h of bedtime. Positive practice at bedtime after a wet night. Extra fluids and holding stop	Until 7 consecutive dry nights	7 consecutive dry nights → Stage 3
3. Normal routine	Alarm removed; no wakings; morning bed check; a wet means the child remakes the bed and does 20 positive-practice trials that evening	Until 14 consecutive dry nights	Two wets within one week → back to Stage 2 until 7 dry nights; 14 consecutive dry nights → end

[source: Bollard 1982]

3. Guiding principles

Assess before you condition. Practical meaning: take a history, a bladder/voiding diary, check bowels and red flags, and treat constipation and daytime symptoms before starting an alarm [source: Nevéus et al. 2020].
Contingency is everything. Practical meaning: the alarm must sound as wetting begins and the child must be fully awake before going to the toilet; a half-awake child silencing the alarm breaks the pairing [source: GPnotebook summary of NICE; Nevéus et al. 2020].
Every night, no interruptions. Practical meaning: no 'nights off' during active training; plan around holidays and sleepovers before starting [source: Nevéus et al. 2020].
The parent is the first alarm. Practical meaning: in early weeks most children sleep through the alarm, so a parent must be ready to go in and wake the child at once [source: Nevéus et al. 2020].
No blame, no punishment. Practical meaning: do not use systems that punish or remove rewards; screen out or first work with families who are angry with the child. Shaming worsens wetting and adherence [source: NICE CG111 IFP; Atlas risk note].
Reward agreed behaviour, not dryness. Practical meaning: reward things the child controls, such as drinking well, voiding before bed, responding to the alarm and helping with sheets [source: NICE CG111 IFP].
Child as active participant. Practical meaning: give the child age-appropriate jobs (resetting the alarm, recording, changing the sheet) framed as practice and responsibility, not penance [source: Bollard 1982; Houts 2005 entry; framing is synthesis].
Whole-household consistency. Practical meaning: everyone who looks after the child overnight, including siblings and the other household in separated families, knows the plan and agrees to it [source: Houts 2005 (FSHT Family Support Agreement)].
Decide on data. Practical meaning: keep nightly records (wet or dry, patch size, woke to alarm or not, number of wets) and use the 4–6-week and 3-month review rules to continue, stop or switch [source: NICE CG111; Nevéus et al. 2020].
Plan for relapse. Practical meaning: tell families at the start that relapse is common and usually responds to retreatment; consider overlearning to lower it [source: GPnotebook; Houts, Peterson & Whelan 1986].
Weigh the burden. Practical meaning: choose the least demanding effective option. Offer the alarm alone first and keep DBT-style additions for selected cases, since DBT is labour-intensive and NICE advises against it [source: Bollard 1982; NICE CG111; synthesis].

4. Intervention inventory

Part A covers the alarm (bell-and-pad) procedures and Part B covers the dry-bed training components. All example wording is illustrative: neither Mowrer nor Azrin published scripts in the sources. [source for Part A: Nevéus et al. 2020; NICE CG111 ch. 12 and IFP; GPnotebook; Bollard 1982]

Part A: Bell-and-pad (urine alarm) training

A1. Pre-treatment assessment and suitability screen

Purpose / when: Before any alarm, to rule out conditions the alarm cannot fix and to check the family can sustain nightly work.
Steps: (1) History: onset (primary, or secondary after 6+ months dry), daytime urgency, frequency or wetting, bowel habit (check constipation with Rome IV criteria), sleep and snoring, behaviour (ADHD), previous treatments. (2) Ask the family to keep a voiding chart: wetting for at least 1 week, plus daytime voided volumes and fluid intake for at least 2 days. Weighing nappies or pads to estimate night urine output for about a week is useful. (3) Arrange a urine dipstick through the medical team if wetting is secondary, daytime symptoms are present or there are warning signs. (4) Red flags that need medical referral before behavioural work: weight loss, excessive thirst, difficulty voiding, recent-onset secondary wetting, heavy snoring or apnoeas. With secondary enuresis, also consider stressors and safeguarding [synthesis on safeguarding wording]. (5) Family suitability: how often wetting happens (alarm is poor value under 1–2 wet nights a week), parental coping, any anger, blame or punishment, room sharing, parental sleep problems. (6) If nocturnal polyuria with normal daytime volumes is found, ICCS suggests desmopressin first via a prescriber. Low maximum voided volumes with normal night output favour the alarm.
Example language (illustrative): "Before we use an alarm, I want a week of records so we can see whether this is mainly a sleep-waking problem, a bladder-size problem or a lot of urine at night. The right treatment depends on which."
Watch for: Hidden constipation; parents who already punish wetting (treat that first, or do not start an alarm); a teenager who is ashamed and will not keep a diary (offer a private, simple format).

A2. Rationale and demystifying talk

Purpose / when: At set-up, to remove blame and build motivation in both the child and the parents.
Steps: (1) Explain that bedwetting is common and involuntary, and that many children grow out of it. (2) Explain the mechanism in child-friendly terms: the alarm teaches the brain to notice a full bladder during sleep, so the child wakes or holds on. (3) Set expectations: early weeks are hard work, change is gradual (smaller patches before dry nights), and many weeks may be needed. (4) Say that relapse can happen and is usually fixed by a shorter second round. (5) Ask the child what they want, for example sleepovers or camp, and link it to the plan.
Example language (illustrative): To the child: "Your body isn't doing anything wrong on purpose. Your brain just hasn't learned yet to listen to your bladder while you sleep. The alarm is a coach that shouts 'now!' at exactly the right moment." To the parents: "Nobody wets the bed deliberately. Being cross makes it harder, not easier."
Watch for: Parents describing the child as lazy or defiant (see A8 and Section 5); a child who is visibly ashamed (keep the session matter-of-fact).

A3. Choosing and setting up the device

Purpose / when: At set-up.
Steps: (1) Choose a type: a bed pad and bell (sensor mat under a draw sheet) or a body-worn alarm (small sensor between two snug pairs of underpants, unit clipped to the pyjama top). One trial found similar results for the two types. Use a vibrating alarm for a child with hearing impairment, or where a sound would wake a sibling [sibling point is synthesis]. Wireless alarms that sound in the parent's room exist [uncertain: not in the sources]. (2) Demonstrate the device thoroughly to child and parents: wet the sensor with a little water, let the alarm sound, switch it off, dry the sensor, reset. (3) Check the volume is loud enough to wake a parent if the child sleeps through. (4) Plan the bed: protective sheet, spare sheets and pyjamas laid out, a night light, a clear path to the toilet. (5) Agree who switches the alarm on each night (usually the child, checked by the parent).
Example language (illustrative): "Let's make it go off now, in daylight, so it isn't a shock tonight. You switch it off, then show me the whole routine."
Watch for: False alarms from sweat or a badly placed sensor (see Section 5); skin irritation where the sensor touches. Older devices caused harm such as electrode ulcers, so use only current approved devices [source: Bollard 1982].

A4. The alarm response routine (rehearsed)

Purpose / when: The core of conditioning. Teach it at set-up and rehearse it on the first evening.
Steps (each time the alarm sounds): (1) Wake fully: get up and stand. (2) Switch off the alarm. (3) Walk to the toilet and finish urinating there. (4) Return, change into dry pyjamas and change the sheet, or put a dry towel down if a full change is impractical [synthesis]. (5) Dry or replace the sensor and reset the alarm. (6) Go back to sleep. (7) Record the event in the morning (A6). In daytime rehearsal: the child lies in bed with lights off, the parent sets off the alarm, and the child runs through steps 1–5. Repeat 2–3 times [rehearsal format is synthesis; DBT's positive practice is a structured version, see B2].
Example language (illustrative): "Alarm. Feet on the floor. Off. Toilet. Fresh pyjamas. Reset. Back to bed. Say it with me."
Watch for: The child switching the alarm off and going back to sleep wet. This is the commonest failure and means the child was not fully awake. Check wakefulness (A5).

A5. Parental waking to the alarm

Purpose / when: From night one, until the child reliably wakes to the alarm alone. In early weeks most children do not wake by themselves.
Steps: (1) A parent sleeps within earshot or uses a remote receiver. (2) When the alarm sounds, the parent goes in at once. (3) Wake the child fully: sit them up, say their name, turn on a light, and check they are awake by asking a simple question or having them say what they are doing. (4) Have the child do the routine themselves, guiding only as needed. (5) Gradually do less as the child begins to wake first. Note that waking happens in response to the alarm. Scheduled waking or lifting without an alarm is a different method that NICE says does not produce lasting dryness.
Example language (illustrative): Parent at night: "Alarm's gone, love. Stand up. Tell me where you're going." Clinician to parents: "Half-awake doesn't count. If they won't remember it in the morning, the lesson didn't land."
Watch for: Parents letting the child sleep on to protect sleep, or carrying a sleeping child to the toilet. Both break the contingency. Watch also for exhausted parents (see Section 5).

A6. Nightly records

Purpose / when: Throughout. Used for reinforcement, review decisions and spotting technical problems.
Steps: Record each morning: dry or wet; number of wets; patch size (small, medium or large); whether the child woke to the alarm, was woken, or did not wake; whether the alarm was on; any toilet trip without the alarm. Keep the chart where the child can see progress. Bring it to every review.
Example language (illustrative): "Smaller patches and waking on your own count as progress, even before dry nights come."
Watch for: Gaps in records, which often signal nights the alarm was off; a pattern of several wets a night (consider a desmopressin combination via the prescriber, see A14).

A7. Reward system for agreed behaviours

Purpose / when: Alongside the alarm, to support adherence. NICE advises rewards for agreed behaviour rather than dry nights. Very-low-quality trial evidence suggests a star chart plus alarm may help.
Steps: (1) With the child, agree 2–4 target behaviours they control: switching the alarm on, voiding before bed, getting up to the alarm, helping change the sheet, drinking well in the day. (2) Use stickers or points, and a small agreed reward at set totals. (3) Give praise straight away. (4) Never remove earned rewards as a penalty for wetting.
Example language (illustrative): "You get a star for getting up when the alarm goes, whether the bed's wet or not. That's the bit you can control."
Watch for: Parents drifting back to 'stars only for dry nights' (gently correct this); rewards losing value (refresh the menu).

A8. Family Support Agreement (behavioural contract; FSHT)

Purpose / when: At set-up, especially with siblings, blended families or more than one household. This comes from Houts' FSHT; only its outline was available [uncertain on exact contents].
Steps: (1) Write down who does what: who switches on, who responds at night, who washes sheets, the child's jobs. (2) Include family rules: no teasing by siblings, no talking about wetting outside the family without the child's consent [synthesis]. (3) Include every adult who looks after the child overnight. (4) The child and parents sign it and put it somewhere visible.
Example language (illustrative): "Let's write the team rules. Who's the night responder this week?"
Watch for: One household not following the plan; sibling teasing.

A9. Clinician check-in and reviews

Purpose / when: ICCS: contact the family at 1–3 weeks to encourage them and fix technical problems. NICE: assess at 4 weeks and reassess at 3 months.
Steps: (1) At 1–3 weeks: is the alarm used every night? Who wakes? Any false alarms? Are records kept? Troubleshoot. (2) At about 4 weeks: look for early signs of response (smaller patches, fewer wets, waking to the alarm, some dry nights). If present, continue. If absent, check fidelity first (A11). If fidelity was good and there is still no response, stop and offer alternatives. (3) At 3 months, if not dry: continue only if still improving and everyone remains motivated.
Example language (illustrative): "Walk me through last night from the moment the alarm went off."
Watch for: Families reporting 'it isn't working' when records show the alarm was off on half the nights.

A10. Stopping at criterion

Purpose / when: When the child reaches 14 consecutive dry nights (the standard success criterion in ICCS, NICE and the research literature).
Steps: (1) Confirm 14 consecutive dry nights on the chart. (2) Either stop the alarm and celebrate, or move to overlearning (A12) if relapse risk is high or the child has relapsed before. (3) Tell the family how to restart quickly if wetting returns.
Example language (illustrative): "Fourteen dry nights in a row: that's the finish line. Keep the alarm in the cupboard, not the bin, just in case."
Watch for: Stopping too early after a short dry run. Hold to 14 consecutive nights.

A11. Fidelity check for apparent non-response

Purpose / when: Before declaring the alarm a failure (ICCS).
Steps: Confirm three things: the alarm was used every night, a parent woke the child at once, and the device worked. Fix any failures and restart the 4–6-week clock.
Example language (illustrative): "Before we give up on the alarm, let's check it had a fair trial."
Watch for: Shame that stops families admitting missed nights. Make it safe to tell you.

A12. Overlearning

Purpose / when: After reaching 14 consecutive dry nights, to reduce relapse. ICCS describes it specifically for children who have relapsed after earlier alarm success. Houts, Peterson and Whelan (1986) found that adding overlearning to the alarm reduced relapse at 3 months. It originates with Young and Morgan (1972).
Steps: (1) Once 14 consecutive dry nights are reached, the child drinks 1–2 extra glasses of water each evening before bed (ICCS wording). (2) Keep the alarm on and keep the response routine. (3) Continue until 14 consecutive dry nights are reached again with the extra fluid, then stop. (4) Do not combine with desmopressin: ICCS states desmopressin is contraindicated here, because of the fluid load. FSHT used a graduated increase in pre-bed water, but the amounts were not verified [uncertain]. Do not invent amounts beyond ICCS's 1–2 glasses.
Example language (illustrative): "You've proved you can stay dry. Now we make the test a bit harder so the skill really sticks."
Watch for: A return of wet nights at first (expected; carry on with the alarm); child distress (explain that this is training, not failure).

A13. Retreatment after relapse

Purpose / when: When wetting returns after success. Relapse rates are commonly reported in the 20–30% range and above (Wikipedia cites 29–69%).
Steps: (1) Restart the full alarm procedure promptly. (2) Use overlearning this time (A12). (3) ICCS suggests a fresh alarm attempt for therapy-resistant children about every 2 years, after a new voiding chart.
Example language (illustrative): "This happens to lots of children. Second rounds are usually shorter."
Watch for: Parents treating relapse as the child's fault.

A14. Combination with desmopressin (liaison, not prescribing)

Purpose / when: For partial or non-response to the alarm; when several wets a night or nocturnal polyuria is present; or when the alarm is not acceptable (NICE, ICCS).
Steps: Refer to or liaise with the prescriber. The psychologist's role is to keep the alarm routine and records going, and to support fluid-timing advice given by the prescriber. No dosing is given here.
Watch for: The family stopping the alarm once medication starts, when the plan was to combine them.

Part B: Dry-bed training (Azrin, Sneed & Foxx 1974, as detailed by Bollard 1982)

Fidelity note: the procedures below follow Bollard's description of Azrin's programme. Azrin's original papers and the parent guide (Azrin & Besalel 1979) are not drawn on [uncertain on fine detail]. Before offering DBT, tell families that NICE advises against such combined programmes and against holding-on training. ICCS says scheduled waking is not curative. Bollard and Nettelbeck (1982) found the components add up: the more components added to the alarm, the better the response, with the waking schedule contributing most. If you use DBT, use it as an informed, second-line choice and drop the punitive elements (see B4 note) [synthesis].

B1. Pre-bed explanation and fluid loading (intensive night)

Purpose / when: The start of the single intensive training night. It increases the number of learning trials by increasing urine production.
Steps: (1) About an hour before bed, explain the whole night's procedure and its rationale to the child and parents. (2) The child has a favourite drink. (3) Put the alarm on the bed. (4) After positive practice (B2), the child drinks again and repeats the instructions back before sleeping. Fluids continue at the hourly wakings (B3). Volumes are not specified in the sources [uncertain]. Do not push fluids in a child with medical conditions affecting fluid balance, or with desmopressin on board [synthesis based on ICCS caution].
Example language (illustrative): "Tonight is a practice night. We'll do lots of practice so your body learns fast. It's a busy night, and tomorrow is a normal one."
Watch for: A child who is anxious about the night; parents who don't understand the plan.

B2. Positive practice of night toileting

Purpose / when: On the intensive night before sleep (20 trials), every evening after a wet night during post-training supervision, and after a wet in the normal-routine stage. It rehearses the full chain from lying in bed to the toilet.
Steps: (1) The child lies in bed with the lights off. (2) The child counts silently to 50 (a lower number for younger children). (3) The child gets up, walks to the toilet and tries to urinate. (4) The child returns to bed. (5) Repeat until 20 trips are done. The parent stays outside the room and counts the trips. On the intensive night, a wet is followed by cleanliness training (B4) and then 20 positive-practice trials before the child goes back to sleep.
Example language (illustrative): "Lie down like you're asleep. Count to 50 in your head, then get up and go, just like your body will when it feels full. That's one. Nineteen to go."
Watch for: Positive practice becoming a punishment ritual delivered in anger. Keep the tone neutral and coaching. Distress or refusal in a young child: shorten the count, praise each trip, consider fewer trials [synthesis; Bollard notes the procedure is demanding].

B3. Hourly wakings with toileting, retention prompts and praise (intensive night)

Purpose / when: Through the intensive night only.
Steps (each hour): (1) Wake the child with minimal prompting and direct them to the toilet. (2) At the toilet door, ask whether they can hold their urine for another hour. If yes, praise them and return them to bed. If no, ask them to wait a few minutes, praise the effort, then let them void, with praise for using the toilet. (3) Back at the bed, the child feels the sheets and is praised for being dry, then encouraged to stay dry for the next hour. (4) The child repeats the instructions, has another drink and goes back to sleep. Note: the holding-on element conflicts with NICE advice against delaying urination. A NICE-consistent adaptation would drop step 2's holding request and let the child void normally [synthesis].
Example language (illustrative): "Feel the sheet. Dry! Brilliant. Let's keep it dry for the next hour."
Watch for: Severe sleep loss for child and parents. Plan a quiet next day. A child who becomes upset or disoriented when woken.

B4. Cleanliness training after a wet

Purpose / when: After every wet, on the intensive night and in later stages. The child takes responsibility for restoring the bed.
Steps: (1) The alarm wakes the child; the trainer or parent wakes them if the alarm does not. (2) The child finishes urinating in the toilet. (3) The child changes into dry pyjamas, takes the wet sheets to the laundry, dries the pad and remakes the bed. (4) On the intensive night, 20 positive-practice trials follow (B2). In the original procedure the child is also reprimanded and told the accident shows they need more practice. Omit the reprimand. NICE says do not use punishment, and shaming is a known risk that worsens wetting [synthesis based on NICE CG111 IFP; Atlas risk note]. Present the clean-up as matter-of-fact responsibility. FSHT also includes a cleanliness-training component; its details were not verified [uncertain].
Example language (illustrative): "OK, the alarm caught it. Sheets in the basket, pad dried, fresh pyjamas. You know the routine."
Watch for: The parent's tone. If cleanliness training feels like a penalty to the child, increase praise for the routine and check parental anger.

B5. Graduated waking schedule (post-training supervision)

Purpose / when: From the night after the intensive night until 7 consecutive dry nights. It fades night-time support gradually.
Steps: (1) Keep the alarm on; wets are handled as in B4. (2) One parental waking per night, first set at about 3 hours after the child's bedtime. (3) After each dry night, move the next evening's waking 30 minutes earlier. (4) Stop wakings once the scheduled time falls within 1 hour of bedtime. (5) Stop extra fluids and holding-on encouragement. (6) After a wet night, the child does positive practice (B2) at bedtime the next evening. (7) Continue until 7 consecutive dry nights, then move to normal routine (B7). Bollard does not specify whether the waking time moves later after a wet night [uncertain].
Example language (illustrative): Parent: "Dry last night, so tonight's wake-up moves earlier: 9:30 instead of 10."
Watch for: Parents who skip the waking or forget to move it; record the time on the chart.

B6. Social reinforcement by family and significant others

Purpose / when: Throughout post-training supervision and normal routine.
Steps: (1) Parents praise dryness and correct toileting as much as possible. (2) Invite relatives and other important people to praise the child too, with the child's consent [consent is synthesis]. (3) Combine with a NICE-style behaviour reward chart (A7) if desired [synthesis].
Example language (illustrative): "Grandma asked me to tell you she's really proud of your dry week."
Watch for: A child who is embarrassed by others knowing. Restrict praise to people the child chooses.

B7. Normal routine: morning check, contingent practice and reinstatement rule

Purpose / when: After 7 consecutive dry nights, until 14 consecutive dry nights.
Steps: (1) Remove the alarm and stop wakings. (2) Parents check the bed each morning. (3) If wet, the child remakes the bed and that evening does 20 positive-practice trials before bed. (4) Two wets within one week means returning to post-training supervision (B5) until 7 consecutive dry nights again. (5) End training at 14 consecutive dry nights.
Example language (illustrative): "Two wets this week means we go back to the alarm stage for a bit. That's the plan we agreed, not a punishment."
Watch for: Families who see stepping back as failure. Frame the reinstatement rule as built-in, from the start.

B8. Retention control (bladder-holding) training

Purpose / when: A component in some DBT trials (Bollard & Nettelbeck 1982) and in FSHT (Houts). The child practises delaying urination during the day to increase functional bladder capacity. Exact parameters are not specified in the sources [uncertain].
Status: NICE advises against programmes involving holding on or stopping the flow. effectivechildtherapy.org rates it 'tested and does not work'. Bollard and Nettelbeck found its effect alone non-significant. Not recommended. Listed for completeness only. No steps are given, because current guidance advises against the procedure.
Watch for: Families who have heard of it. Explain why it is not used, and refer any concern about small bladder capacity to the medical team for daytime bladder assessment.

5. Handling problems

Sources address a few of these directly: alarm not waking the child, false alarms, the child switching the alarm off, parents forgetting, dropout, non-response, relapse, and family coping [source: Bollard 1982; Nevéus et al. 2020; NICE CG111]. The rest is marked [synthesis].

Child sleeps through the alarm. This is expected in early weeks [source: Nevéus et al. 2020]. The parent must go in and wake the child fully every time. Check volume and placement; move the unit closer to the head or use a body-worn or vibrating alarm [synthesis]. Persisting after about 4–6 weeks with good fidelity counts as non-response (below).
Child switches off the alarm and goes back to sleep. Named in the sources as a common failure [source: Bollard 1982]. Place the off switch out of reach so the child has to stand to reach it. Have a parent respond. Rehearse the routine in daytime (A4). Reward getting up, not dryness [synthesis].
False alarms (sweat, malfunction). Named in sources [source: Bollard 1982]. Check the sensor, connections and battery. Lighter bedding or pyjamas if night sweating. Reposition the sensor. Replace a faulty unit promptly, since false alarms quickly erode motivation [synthesis].
Alarm not switched on, nights missed. Named in sources [source: Bollard 1982]. Make switching on a rewarded bedtime behaviour (A7). Put the alarm step on a bedtime checklist. A parent checks it at lights-out. Records show gaps [synthesis].
Several wets a night. ICCS: an alarm alone may not be the best first choice. Liaise with the prescriber about combining with desmopressin. Do the voiding chart and check for nocturnal polyuria [source: Nevéus et al. 2020].
No progress at 4 weeks (NICE) or 6 weeks (ICCS). Check fidelity first (A11). If fidelity was good, stop the alarm and offer desmopressin or a combination via the prescriber. If the child partially responds to the combination, NICE suggests desmopressin alone. A fresh alarm trial is reasonable about every 2 years [source: Nevéus et al. 2020; GPnotebook summary of NICE].
Improving but not dry at 3 months. Continue only if wetting is still improving and the family remains motivated [source: GPnotebook summary of NICE].
Relapse after success. Restart the alarm promptly and add overlearning (A12, A13). Normalise relapse in advance [source: Nevéus et al. 2020; Houts, Peterson & Whelan 1986].
Parental anger, blame or punishment ("he's lazy", "she does it on purpose"). NICE: an alarm is inappropriate where parents express anger, negativity or blame. First work with the parents: education about involuntary wetting, how shame affects adherence, and replacing punishment with behaviour rewards. Start the alarm only when the parents can respond calmly. If you are concerned about harsh punishment, follow safeguarding procedures [source: NICE CG111; NHS NEL pathway; parent work is synthesis].
Family exhaustion and broken sleep. A known cause of dropout, with about a third dropping out in older series [source: Bollard 1982]. Rotate the night responder. Start during a calm period, not before exams or a house move. Use a remote receiver in the parent's room. Shorten the intensive phase. Prefer alarm-alone over DBT for stretched families [synthesis]. Bollard reports one DBT case stopped because the mother could not cope [source: Bollard 1982].
Shared bedroom or sibling disturbance. ICCS lists room sharing as a reason the alarm may be less suitable. Options: a vibrating or body-worn alarm, temporary sleeping rearrangements, involving siblings in the support agreement (A8) [source: Nevéus et al. 2020; options are synthesis].
Resistance or low motivation in the child, especially older children and teenagers. Use motivational talk tied to the child's own goals (camps, sleepovers). Give the young person control of the device and records. Offer a body-worn or vibrating alarm for privacy. NICE notes that self-waking with a phone or alarm clock may help young people who have not responded to treatment. This is a short-term coping step, not alarm conditioning [source: NICE CG111 IFP; motivational framing is synthesis].
Shame and emotional distress. Keep sessions matter-of-fact. Make sure no-one outside the agreed circle is told. Watch for low mood or bullying and address it in its own right [synthesis].
Holidays, sleepovers and interruptions. ICCS requires nightly use without interruption. Plan the course to avoid known gaps. For one-off events, use pragmatic measures (protective pants; NICE allows short-term waking, for example on holiday), then resume [source: NICE CG111 IFP; Nevéus et al. 2020; planning is synthesis].
Daytime symptoms, constipation, or secondary-onset wetting. Pause and refer for medical assessment. Treat constipation before enuresis treatment. Red flags (thirst, weight loss, voiding difficulty, snoring or apnoeas, recent secondary onset) need medical work-up. With secondary enuresis, explore stressors and consider safeguarding [source: Nevéus et al. 2020; safeguarding is synthesis].
ADHD or developmental differences. ICCS notes ADHD may lower alarm success. Use more structure: visual routine cards, immediate rewards, closer clinician contact [synthesis]. Azrin's dry-bed method was first developed for adults with intellectual disability in residential settings, with staff delivering it [source: Azrin, Sneed & Foxx 1973 abstract]. Adapt it with care and an ethics review of any aversive elements [synthesis].
DBT-specific: distress during positive practice or cleanliness training. Remove reprimands. Shorten the count. Praise every trial. If the child experiences it as punishment, or parents use it punitively, stop DBT and revert to alarm-alone with behaviour rewards [synthesis based on NICE].
DBT-specific: the intensive night is not feasible at home. Use the alarm alone first. Bollard and Nettelbeck's component data suggest that the alarm plus the waking schedule (B5) carries much of DBT's added benefit, though NICE cautions against waking routines [source: Bollard & Nettelbeck 1982 abstract; NICE CG111 IFP] [uncertain: the guidance conflicts].
Skin irritation from the sensor or pad. Check fit and placement; use cotton underwear layers; consult the medical team if it persists [synthesis].
Rupture with the clinician (family feels blamed for 'failure'). Name it directly. Share responsibility for the plan: "the plan didn't fit your family yet" rather than "you didn't do it". Revisit suitability and options together [synthesis].
