Bedwetting
common, treatable, and never the child's fault
Around one in six children is still wetting the bed at five, and one in twenty at ten. It is not laziness, attention-seeking or a behavioural problem, and children cannot control it — they are asleep. It responds well to treatment, and treatment can start from around five years old.
Arrange assessment promptly if your child
- has started wetting again after six months dry
- is also wetting during the day, or straining to pass urine
- is drinking and passing urine excessively, or losing weight
- has pain passing urine, fever or smelly urine
- is constipated or soiling
- has snoring with pauses in breathing, or new behavioural change
Bedwetting that starts again after a dry period, or occurs with daytime symptoms, needs assessing rather than treating as ordinary bedwetting. Excessive thirst and urination in a child requires same-day testing for diabetes.
Why it happens
- the bladder produces more urine overnight than it can hold, because the hormone that concentrates urine at night has not matured
- a small or overactive bladder
- very deep sleep — the child does not rouse to a full bladder
- constipation, which is present in a large proportion and is the single most commonly missed factor
- It is strongly hereditary — if both parents wet the bed, the chance is high. Telling a child this often helps enormously.
Punishment and reward charts for dry nights do not work
A child cannot choose to be dry, so rewarding dry nights rewards luck and punishes something outside their control — and it damages confidence, which makes matters worse. If you use a chart, reward the behaviours: drinking well during the day, using the toilet before bed, helping change the sheets without fuss. Never shame, never involve siblings, and never make it a family topic of conversation.
Check the basics first
- Treat constipation — a loaded bowel presses on the bladder. Fixing this alone resolves a meaningful proportion of cases.
- Drink more during the day, not less. Restricting fluid shrinks bladder capacity and makes things worse. Aim for six to eight drinks spread through the day, most before 5pm.
- Cut fizzy and caffeinated drinks, including cola and chocolate drinks in the evening.
- Toilet before bed, and again just before the parents' bedtime if the child is easily roused.
- Easy night access — a night light, a clear path, and no fear of the dark or of stairs.
- Stop pull-ups at night once treatment starts, if the child agrees; they can mask progress.
Treatment
- A bedwetting alarm is first-line for children over about seven who are motivated. It sounds at the first drop and gradually trains the brain to wake or to hold on. It requires commitment from the whole household for one to three months, and someone needs to help the child wake at first.
- Desmopressin reduces overnight urine production. It works quickly, which makes it ideal for school trips and sleepovers, but wetting usually returns when it is stopped unless used as part of a longer plan. Fluid must be restricted for eight hours after the dose, and it should be omitted if the child is unwell or vomiting.
- Where these do not work, further assessment and specialist referral are appropriate.
Practical help
- Waterproof mattress protector, and a second one under the first with a sheet between — strip one layer at 3am rather than remaking a bed.
- Keep dry pyjamas and a towel by the bed so the child can manage independently.
- Involve the child in changing sheets without it being a punishment.
- For sleepovers and school trips, talk to the host or teacher in advance — and consider desmopressin.
- Reassure your child that many children in their year are in the same position and simply do not say so.
Why come to us. Bedwetting is frequently dismissed as something children grow out of, which leaves families managing it alone for years. We offer unhurried paediatric appointments seven days a week, check the things that actually matter — constipation, urine testing and diabetes screening in-house, bladder ultrasound on site where indicated — and provide alarms, prescribe desmopressin, and set up a plan that fits your household. Children are seen as people rather than problems.
Assessed, and treated — not just reassured
Paediatric appointments seven days a week, urine testing and ultrasound on site.
