Bedwetting in Children (Nocturnal Enuresis): A Parent's Guide

If your child wets the bed, you are not alone, and it is not their fault. Bedwetting (the medical name is nocturnal enuresis) is one of the most common parts of growing up, and for almost every child it gets better with time.

The short answer

  • It is very common. Around 15 to 20% of five-year-olds wet the bed.
  • It is involuntary. Your child is asleep and has no control over it, so it is never naughtiness or laziness.
  • It usually resolves on its own. Only 1 to 2% of teenagers are still affected.
  • Routines help more than restrictions. Keep daytime drinks up, treat constipation, and reward effort rather than punishing accidents.
  • See your GP if it starts again after six dry months, comes with daytime wetting or pain, or is upsetting your child.

What is bedwetting (nocturnal enuresis)?

Nocturnal enuresis means passing urine without meaning to while asleep, in a child old enough to be expected to stay dry at night, generally from about five years of age. The important word is involuntary: your child is deeply asleep and genuinely has no control over what is happening.

Primary bedwetting

The child has never had six months or more of consistently dry nights. This is by far the most common type, and it usually just means night-time bladder control is taking a little longer to develop.

Secondary bedwetting

The child was reliably dry for at least six months, then started wetting again. Because something has changed, this type is more likely to have a specific trigger, such as constipation, a urinary infection, or a stressful event, and it is always worth mentioning to your GP.

How common is bedwetting?

Far more common than most parents realise. Because it happens behind closed doors, families often feel they are the only ones dealing with it, when in reality most classrooms include children who wet the bed.

1 to 2%of teenagers are affected

That downward trend is the reassuring part. Every year, a large share of children simply grow out of it without any intervention at all. Bedwetting is slightly more common in boys, and it very often runs in families.

What causes bedwetting?

Bedwetting is almost never about drinking too much before bed. In most children it comes down to one or more of three natural, physical causes.

1. The bladder signal does not wake them

Children who wet the bed are often very deep sleepers. The "my bladder is full" message does not rouse them, so the bladder empties before they wake. This arousal response develops with age.

2. The bladder cannot yet hold a full night

A younger bladder may have a smaller working capacity than the volume of urine produced overnight, so it fills before morning. This improves naturally as your child grows.

3. The body makes too much urine overnight

At night the body normally releases a hormone called vasopressin, which tells the kidneys to make less, more concentrated urine. Some children do not yet produce enough of it, so they make more urine than a small bladder can hold until morning.

Other contributing factors

  • Family history: if both parents wet the bed as children, research suggests a child has roughly a 70% chance of doing so too. With one parent it is around 40%.
  • Constipation: a full bowel presses on the bladder and reduces how much it can hold, so treating constipation often improves bedwetting on its own.
  • Bladder irritants: fizzy drinks and anything containing caffeine, including chocolate, can irritate the bladder.
  • A change or a worry: starting school, a new sibling, or an unsettling event can trigger secondary bedwetting.
  • Occasionally a medical cause: such as a urinary tract infection, which is why new or painful wetting should always be checked.

Worth knowing: bedwetting is not caused by poor toilet training, and it is not a behavioural problem. Treating it as misbehaviour tends to make a child more anxious, which can make the wetting worse rather than better.

When should you see a GP?

Most bedwetting simply needs patience, but it is worth booking a chat with your doctor if your child:

  • Is still regularly wetting the bed at seven years or older, and it is bothering them
  • Was dry for six months or more and has started wetting again
  • Also has daytime wetting or accidents
  • Has pain, burning, or cloudy or smelly urine when weeing
  • Is suddenly drinking or weeing far more than usual
  • Is distressed or losing confidence, or it is stopping sleepovers and school camps

Your GP can check for any underlying cause and talk you through the options. The Continence Health Australia also runs a free National Continence Helpline, staffed by nurse continence specialists.

What helps at home

Small, consistent habits genuinely move the needle. These are the practical steps most continence specialists suggest starting with.

  • Keep daytime drinks up. It sounds backwards, but drinking well through the day, around six to eight glasses of water, trains the bladder to hold more. Do not restrict daytime fluids.
  • Ease off drinks in the last hour before bed, especially fizzy and caffeinated ones.
  • Build a toilet routine. Encourage a wee about four to seven times a day, and always one last visit right before lights out.
  • Deal with constipation. Speak to your GP or pharmacist if needed. It is one of the most overlooked causes of bedwetting.
  • Protect the mattress with a waterproof cover, so the occasional accident is quick and calm to clean up.
  • Reward the effort, never punish the accident. Praise dry nights and sticking to the routine, and stay matter-of-fact about wet ones.
  • Keep it private. Let your child decide who knows. Protecting their dignity protects their confidence.

Treatments a doctor might suggest

If your child is older, motivated to be dry, and home routines have not been enough, a GP may recommend one of the following.

  • A bedwetting alarm. A small moisture sensor that sounds at the first drop, gradually teaching the brain to wake to a full bladder. Used consistently over several weeks, it is one of the most effective long-term treatments.
  • Desmopressin. A medicine that mimics the overnight hormone and reduces how much urine the body makes during sleep. It can be useful for camps and sleepovers, and is prescribed and monitored by your doctor.
  • Bladder training and treating constipation. Improving daytime bladder habits and bowel health often improves nights as well.

Whichever path you take, the reassuring headline stays the same: the large majority of children grow out of bedwetting, with or without treatment.

Staying comfortable and confident in the meantime

While your child grows out of bedwetting, the right protection lets everyone sleep properly and keeps their confidence intact, which matters most for sleepovers, school camps and holidays. Modern absorbent pants are a long way from a baby nappy: they are slim, quiet, and look and feel like real underwear, so children stay independent rather than feeling singled out.

Our iD Comfy Junior range is built for exactly this. Soft pull-up pants come in sizes for ages 4 to 15, with a high-absorbency slip for higher needs or a more adjustable fit. A channelled core draws moisture away quickly to help skin stay dry through the night, with double anti-leak barriers positioned for boys and girls.

Comfortable, confident nights while you wait

Questions parents ask

Is bedwetting my child's fault?

No. Your child is asleep and has no control over it. Bedwetting is a stage of development, not misbehaviour, and it responds far better to patience and encouragement than to frustration.

Will my child grow out of it?

Almost certainly. Bedwetting becomes less common every year as children mature, and most stop without any treatment at all. If you are worried, or your child is upset by it, your GP can help.

Should I limit how much my child drinks?

Not during the day. Good daytime hydration actually helps the bladder hold more. Simply ease off drinks in the hour before bed, particularly fizzy and caffeinated ones.

Is it worth waking my child to use the toilet at night?

Lifting a sleepy child to the toilet may keep the bed dry that night, but it does not teach the bladder to wake them on its own, so it is not a long-term fix. A bedwetting alarm, guided by your GP, is what builds that skill.

Are absorbent pants a step backwards?

Not at all. They are a practical way to protect sleep, bedding and confidence while your child grows out of bedwetting. Because iD Comfy Junior looks and feels like normal underwear, it supports your child's independence rather than undermining it.

Could bedwetting be a sign of something serious?

It is rarely a sign of a serious problem. However, wetting that begins suddenly after a long dry period, or comes with pain, unusual thirst, or daytime accidents, should always be assessed by your GP so any underlying cause can be ruled out.
