Bedwetting: Why It Happens and What Helps

Waking up to wet sheets is frustrating for parents and upsetting for kids, but bedwetting is one of the most common childhood issues. Many 5-year-olds still wet the bed at least sometimes, and the number drops each year as children grow. It’s almost never deliberate, it’s rarely a sign of anything serious, and there’s a lot you can do to make nights easier while your child’s body catches up.

Why children wet the bed

Staying dry at night depends on three things working together, and in many children one of them is simply still developing:

• Night-time urine production. Most people make less urine at night thanks to a hormone. Some children make more than their bladder can hold.
• Bladder capacity. A bladder that fills quickly or holds less reaches its limit overnight.
• Waking up. Many kids who wet the bed sleep deeply and don’t wake to the signal of a full bladder.

Other factors:

• Family history. Bedwetting often runs in families; if a parent wet the bed as a child, it’s more likely.
• Constipation. A full bowel presses on the bladder and is a common, overlooked cause.
• Boys are affected more often than girls.
• Less often: urinary infections, diabetes, sleep apnea or stress.

Primary vs. secondary bedwetting

• Primary: your child has never been reliably dry at night. This is the most common type and usually improves with time.
• Secondary: your child starts wetting again after being dry for six months or more. This is worth a doctor’s visit, because it can be linked to infection, constipation, diabetes or stress, such as a new sibling, a move or problems at school. Our guide to preparing for a new sibling covers regression around a new baby.

What helps

1. Spread drinks through the day. Kids who drink little at school often catch up in the evening. Aim for regular drinks through the day and fewer in the hour or so before bed.
2. Skip caffeine and fizzy drinks, especially in the afternoon and evening.
3. Bathroom before bed, as the last step of the routine, and again just before sleep if they’re still awake. Our bedtime routine guide shows where it fits.
4. Make night trips easy. A night light, a clear path and a potty or bathroom nearby help a sleepy child get there.
5. Treat constipation. Plenty of fiber, fluids and regular toilet time help; talk to your pediatrician if it’s a problem.
6. Protect the bed. A waterproof mattress cover, layered sheets and a spare set of pajamas make cleanup quick.
7. Keep cleanup calm and matter-of-fact. Older kids can help strip the bed as a routine, not a punishment.

What doesn’t help

• Punishment, shaming or teasing. Bedwetting isn’t something children can control by trying harder, and shame makes things worse. Make sure siblings don’t tease either.
• Strict fluid restriction. Cutting drinks all day can cause constipation and doesn’t address the cause.
• Rewards for dry nights. Kids can’t directly control dry nights. Reward what they can control instead, such as drinking well during the day, using the bathroom before bed and helping with cleanup.

Waking a child to pee during the night can reduce wet sheets in the short term, but it doesn’t teach the body to stay dry.

Bedwetting alarms

A bedwetting alarm has a small moisture sensor that sets off a sound or vibration at the first drops, training the child to wake up, or to hold on, when the bladder is full. Alarms work for many children aged 7 and up, but they need commitment:

• It can take several weeks before you see progress.
• A parent often needs to help the child wake up at first.
• Families usually continue until the child has been dry for a couple of weeks in a row.

Your pediatrician can advise whether an alarm suits your family.

Medicine

A medicine called desmopressin reduces the amount of urine made at night. It can be helpful for sleepovers and camps, or when an alarm isn’t suitable, but wetting often returns when it’s stopped. It must be used exactly as prescribed, including limits on drinking around bedtime. Only use medication under your doctor’s guidance.

When to see your pediatrician

• Your child is 7 or older and still wets the bed regularly.
• Wetting starts again after six months or more of dry nights.
• There’s pain or burning when peeing, pink or red urine, or cloudy, strong-smelling urine.
• Your child is unusually thirsty or peeing very often.
• There are daytime accidents, constipation or soiling.
• Your child snores loudly or seems to stop breathing in sleep.
• Bedwetting is upsetting your child or affecting friendships and sleepovers.

Sleepovers and camps

Bedwetting doesn’t have to mean missing out. Discreet absorbent underwear, a sleeping bag with a waterproof liner, a plan with a trusted adult and, if your doctor agrees, short-term medication can all help. Pack a spare set of clothes in a separate bag.

Frequently asked questions

At what age should a child stop wetting the bed?

There’s a wide normal range. Many children are dry at night by 5 or 6, but plenty take longer. Doctors usually start treatment around age 7, or earlier if it’s bothering the child.

Is bedwetting caused by stress?

Stress rarely causes bedwetting on its own, but it can trigger a return of wetting in a child who was dry. Most bedwetting has physical causes.

Should my child wear pull-ups at night?

They can make nights easier, especially for younger kids and sleepovers. Some children feel more motivated without them; follow your child’s lead and your pediatrician’s advice.
