The good news is there are lots of things you can do to work out why bedwetting regression is happening and make it stop.

What is bedwetting regression?

Bedwetting regression is most commonly known as secondary wetting, or sometimes "sudden onset wetting". This refers to when children begin to have night-time wetting after at least 6 months of dry nights.

If bedwetting starts up again or happens suddenly out of the blue, the first thing to do is make sure it's not being caused by another medical condition. A doctor can check your child for signs of a urinary tract infection (UTI), Type 1 Diabetes, constipation or stress at home or school.

Finding out the reasons for bedwetting makes it much easier to help your child stop bedwetting, whether they've always done it or the wet nights have recently started again. This is the same if they are wet every night or just a few times a month.

When does bedwetting regression usually occur?

If your child starts to wet the bed again, try to stay calm and be patient with them. Remember that they aren't doing it because they're being lazy or naughty. The more upset and anxious they feel, the more likely it is they will be wet at night. Reassure your child that together, you can be bedwetting detectives and sort it out for good!

Helping them to understand the reasons why bedwetting happens is a great place to start. You can then make a checklist together of things to look out for, such as drinking too late in the evening or not having enough to drink in the daytime.

What causes bedwetting in a 3-year-old?

Bedwetting in pre-schoolers is very common and completely normal. Some children just take a little longer than others to stay dry throughout the night.

"I assumed my little boy would become dry at night straight after he potty trained when he was 2 and a half. He actually didn't stop until just before he started school. I now know this is common, and I needn't have got myself so stressed out!"

- Sam, Parent

One of the most common causes of a bedwetting relapse at this age is constipation. This is something that affects 1 in 3 children. Poo problems often start at the potty training stage. A full bowel affects the amount of urine your child's bladder can hold, and constipation can also make the bladder empty while your child is sleeping.

How can I help my toddler with night-time accidents?

  • Check your child for signs of constipation and get this treated if it's a problem for them.
  • Make sure they are having enough to drink. At 3 years old, your child should be having 6-8 cups of water-based fluid (average cup size of 150-175ml) spread throughout the day, on top of any milk they have.
  • If they are still having milk before bedtime, get them into the habit of having it just after their tea and not right before they go to sleep.
  • Help them to get into a routine of using the potty or toilet before they go to sleep.

What causes bedwetting regression in a 6-year-old?

Once you've checked there's no underlying physical cause behind your child's night-time bedwetting, together you can work out what the triggers could be. A change in their routine and big life events such as starting school can cause bedwetting regression. The more tired your child gets, the harder it can be for them to wake up when their bladder needs emptying at night.

How can I help a 6-year-old with bedwetting?

Alina Lynden, an expert from ERIC, the national charity dedicated to improving children's bowel and bladder health, suggests the following.

  • Talk to your child about how common bedwetting is and reassure them that they haven't done anything wrong. Explain there are ways to keep their bladder working as it should, day and night.
  • Try to have a regular, calm bedtime routine which includes a trip to the loo just before the lights go out.
  • Make sure they are having enough to drink during the school day and stop drinking at least an hour before bedtime. At this age they need between 6-8 drinks of around 175ml each.

What causes bedwetting regression in a 7-8 year-old?

It can be a lot harder and more upsetting for children to deal with bedwetting as they get older.

"I don't like it when I wet the bed because it makes me feel like I'm a baby again. My little sister doesn't do it, so why do I?"

- Imogen, 8 years old

How can I help a 7-8 year old with bedwetting?

As your child gets older, there are some other things you can do to help. Alina Lynden of ERIC recommends trying some of the following approaches.

  • Try to make sure your child doesn't feel they can't do all the same things their friends can, like school camp and sleepovers.
  • Help them understand why drinking plenty during the school day gives their bladder practice in filling and emptying properly, and helps it hold more wee when they're asleep.
  • At this age they need between 6-8 drinks of around 200ml each. Some children find fizzy and caffeinated drinks irritate their bladder and make bedwetting worse, so it's best to avoid these.
  • Reward each step along the way - getting the drinking right, doing a bedtime wee, using the toilet at night - to keep them positive. You're not rewarding a dry night (which they can't control), but rewarding them for keeping to their routine.

Why is my teenager experiencing bedwetting regression?

Bedwetting and bedwetting regression gets much less common as children get older, affecting 1 in 75 teenagers. Exam stress, hormonal changes and friendship issues mean there can be an awful lot going on in the life of your teenager, and this can sometimes trigger instances of bedwetting.

How can I support my teenager with bedwetting?

As children get older and into their teens, it can be harder to talk to them about things like bedwetting regression. They may secretly worry about it and blame themselves.

"I still feel guilt, shame, humiliation and have lost my self-esteem. Sometimes I feel quite helpless and hopeless."

- George, 14 years old

Hiding wet sheets and going into denial is a common way for young people to cope with the embarrassment and confusion they feel. This is completely normal, and you can help them through it by being patient and understanding. There are lots of ways to help and support them, including the following.

  • Encourage them to keep a wet versus dry night diary. This can help spot patterns and triggers, such as eating later than normal or not drinking as much in the daytime.
  • Make sure they drink enough: teenage girls should be drinking 1.5-2 litres and boys should be having 2-2.5 litres of water-based fluid, and more if they're doing lots of exercise or the weather is hot.
  • Help them avoid looking at their phone or playing computer games in the hour before sleep, as the blue light can interrupt the natural release of hormones that help us sleep. Suggest they unwind with a book or music with the lights low.
  • Book an appointment with your doctor so they can be assessed and you can talk about possible treatments.

"My advice to teens like me is to be yourself and speak to family and trusted adults. Also, networking with others who share similar experiences can be really helpful."

- George, 14 years old

Can I prevent bedwetting regression?

Helping your child get into good habits around drinking plenty, not getting constipated and following a bedtime routine can help to avoid night-time wetting accidents. Bedwetting happens when they're asleep, so it's outside of their conscious control. Support your child not to blame themselves if they wet the bed. If they're wet most nights and it's making them feel upset, talk to your doctor so they can check for any underlying medical conditions and explore treatment options.

Helping your child through bedwetting regression

If your child starts to wet the bed again, reassure them they're not the only one this happens to and it's nothing they've done wrong. It can be frustrating and stressful, especially for older children, so talk to them and find out how they're feeling. Try to be patient and understanding.
