Bedwetting in Children: Why It Happens, What Helps and When to Get Support

Bedwetting is never a child’s fault, and it’s far more common than most parents realise. Many school-age children still wet the bed sometimes, and most grow out of it. But you don’t have to just wait. There’s effective help, especially once a child is about five or older.

Imagine your seven-year-old bursting into tears because they’ve been invited to their first sleepover and they’re terrified of wetting the bed. They’ve tried so hard, and they feel ashamed. You’ve tried limiting drinks and lifting them at night, and nothing works. What your child needs most right now is to hear that it’s not their fault, and that there’s a plan.

Why bedwetting happens

• The body makes too much urine at night, because levels of a hormone that reduces night-time urine haven’t matured yet
• A bladder that’s smaller or more “overactive” than average
• Very deep sleep, so the child doesn’t wake to the full-bladder signal
• It runs in families
• Constipation, which presses on the bladder

Practical tips that help

• Don’t restrict daytime drinks. Children should drink well during the day, spread out, with less in the hour before bed.
• Avoid fizzy and caffeinated drinks, such as cola and tea, especially in the evening.
• Regular toilet trips during the day and just before bed.
• Treat constipation if it’s present.
• Make night-time toilet trips easy with a night light and a clear path.
• Praise effort, not dry nights, such as drinking well or going to the toilet before bed. Never punish or shame.
• Use waterproof mattress covers to reduce stress for everyone.

Treatments

• Enuresis alarm: a sensor that sounds when it detects wetness, teaching the brain to wake to a full bladder. It takes commitment over several weeks but has good long-term success.
• Medicine: desmopressin reduces urine made at night. It can be useful for sleepovers and camps, but a doctor needs to prescribe it and explain the fluid rules that come with it.

But when should we see a nurse or doctor?

Get support if your child is five or older and it’s affecting them or the family, or sooner if they start wetting again after being dry for six months or more, are wetting during the day, are very thirsty, have pain when peeing, are losing weight, have constipation, or seem unwell or upset. New bedwetting can be a sign of a urine infection, diabetes, or emotional stress, including bullying or problems at home. School nurses and continence nurses are often a great first point of contact.
