Is my child doing it on purpose?
No. They are asleep when it happens and have no control over it.
This is the single most important thing to understand, and getting it wrong causes lasting harm to a child's confidence.
Should I limit drinks in the evening?
Taper in the last hour before bed, but do not restrict during the day — that is the common mistake.
Concentrated urine irritates the bladder and reduces its capacity, so daytime restriction usually makes bedwetting worse.
Could constipation really be the cause?
Yes, and it is the most commonly missed one. A loaded bowel presses on the bladder and reduces how much it can hold.
Treating it resolves a meaningful share of bedwetting on its own, which is why it should be asked about first.
At what age should I do something?
Bedwetting under five is within the normal range and does not need treating.
From five upwards it is reasonable to act, particularly if it is bothering your child.
My child was dry and has started again. Why?
That is secondary bedwetting and it always deserves assessment.
Urine infection, constipation, threadworms, new diabetes or something emotional are the usual explanations, and most are straightforward to address.
Do alarms work?
Yes — they are first-line for lasting dryness. They train the brain to respond to a full bladder.
They take several weeks and disturbed nights for everyone, so they need commitment, but the results last.
What about medication?
Desmopressin reduces overnight urine production and works quickly. It is ideal for sleepovers, trips and holidays.
It treats rather than retrains — wetting usually returns when it is stopped, which is worth knowing in advance.
Should I use a star chart?
Yes, but reward the right thing. Reward drinking well, using the toilet before bed, and helping change sheets.
Never reward dry nights. The child cannot control those, so the chart becomes another way to fail.
Will they grow out of it?
The great majority do — roughly 15% of children who wet the bed stop each year without any treatment.
That is not a reason to do nothing if it is affecting your child's confidence or stopping them going on sleepovers. Treatment works, and waiting has a cost too.
