Short answer: Being dry at night often comes months or even years after being dry in the day, and many children under five still wet the bed. It's not laziness and it's not your child's fault: they may not wake to the signal of a full bladder, or may make a lot of urine at night. Never punish. Make sure your child drinks enough during the day, uses the toilet regularly and before bed, avoid caffeine, and protect the mattress. See a GP if home measures haven't helped, or if your child starts wetting again after being dry for six months or more.
Daytimes have been fine for months. Not a single accident. And still the bed is wet most mornings, and your child is starting to feel embarrassed about it. Being dry in the day and being dry at night are two quite different things.
Why night-time comes later
Staying dry in the day is largely a skill: your child feels the urge and goes to the toilet. Staying dry at night depends on things your child can't control, such as whether they wake when their bladder is full, and how much urine their body makes during sleep. The NHS lists not feeling the need to pee while asleep and making too much urine at night as common causes, along with stress at home or school.
Bedwetting is also common and often runs in families. If you or your partner wet the bed as a child, it's worth mentioning to your GP — and to your child, who may find it reassuring.
Your child isn't wetting the bed on purpose. They're asleep — and the signal from their bladder isn't getting through yet.
What helps at home
- Enough to drink during the day. Spread drinks through the day rather than cutting them out; a well-hydrated bladder works better.
- Regular toilet trips, around 4 to 7 times a day, including just before bed.
- No caffeine: avoid cola, tea, coffee and energy drinks, which make children wee more.
- Easy access to the toilet at night — a night light on the landing, a clear path, or a potty in the room.
- Protect the bed: waterproof covers on the mattress and duvet, and a spare set of sheets ready, so a 3am change takes two minutes.
- Reward the steps they can control, such as using the toilet before bed — not dry nights, which they can't control.
- Stay calm and matter-of-fact. No sighs, no looks. “Let's get you changed” and back to bed.
What doesn't help
- Punishment or telling off. It isn't your child's fault, and the NHS warns it can make bedwetting worse.
- Regularly waking or carrying your child to the toilet at night. It doesn't help in the long term.
- Making it a secret or a joke. Shame does more harm than a wet bed. Make sure siblings know teasing isn't OK.
Pull-ups or night nappies are fine while your child needs them. Many families stop using them for a trial period when they and their child feel ready.
When to see a GP
- You've tried the steps above and your child keeps wetting the bed, and it's bothering them or you.
- Your child has started wetting the bed again after being dry for more than six months — this can be linked to a urine infection, constipation, diabetes or stress.
- There are also daytime accidents, pain when weeing, or your child is very thirsty and weeing a lot.
- Your child snores loudly or has pauses in breathing at night.
Your GP or school nurse can help. Treatments include a bedwetting alarm, which wakes your child when they start to wee, and medicine that reduces how much urine is made at night — sometimes used for sleepovers or school trips. If these don't work, your child may be referred to a specialist.
Above all, protect your child from feeling ashamed. Almost every family deals with this at some point.
