Bed-Wetting (Nocturnal Enuresis): Symptoms, Causes, and Treatment
Updated: 3 days ago
Medically reviewed by Dr. Baraa Alnahhal, MD · Last reviewed: October 2026
Quick Answer
Bed-wetting, or nocturnal enuresis, is passing urine without intending to while asleep, after the age when staying dry at night is expected. It usually reflects normal development, such as small bladder capacity or low night-time anti-diuretic hormone. See a doctor if it continues after age 7. Treatment involves patience, no punishment, lifestyle changes, moisture alarms and sometimes medication.
What the research says
Desmopressin works better than placebo, and about as well as an alarm by the end of treatment. A Cochrane review of 95 studies (8,473 participants) found that desmopressin probably leads to more children achieving 14 consecutive dry nights than placebo (risk ratio 3.18; 95% CI 1.75 to 5.80; 11 studies, 922 participants; moderate-certainty evidence). Versus alarm therapy there was little or no difference in children reaching 14 consecutive dry nights (RR 0.98; 95% CI 0.88 to 1.09; 15 studies, 1,530 participants), but alarm therapy may leave more children dry at follow-up (moderate-certainty evidence). Overall quality of evidence was low or very low (Hahn et al., Cochrane Database Syst Rev, 2025) [3].
Alarms and desmopressin give similar results, with fewer side effects from alarms. An overview of seven Cochrane reviews found no difference between alarm and desmopressin for complete response after treatment (RR 1.30; 95% CI 0.92 to 1.84), while alarm use was linked to a lower risk of adverse events (RR 0.38; 95% CI 0.20 to 0.71) (Moretti et al., J Pediatr Urol, 2022) [4].
Combination treatment may help when one therapy is not enough. A network meta-analysis of 23 randomized trials (2,424 children) found that desmopressin combined with an anticholinergic such as oxybutynin achieved complete response more often than desmopressin alone, and desmopressin alone had a higher relapse rate than alarm therapy; the certainty of evidence was mostly low to moderate (Chen et al., Pediatr Nephrol, 2026) [5].
What is bed-wetting?
Bed-wetting means passing urine without intending to while asleep, after the age at which staying dry at night can be reasonably expected. It is also called nighttime incontinence or nocturnal enuresis.
Soggy sheets and pajamas, along with an embarrassed child, are a familiar scene in many homes. The important thing to know is that bed-wetting is not a sign of problems with toilet training. It is often just a typical part of a child's development.
Generally, bed-wetting before age 7 is not a concern. At this age, your child may still be developing nighttime bladder control. If your child continues to wet the bed, the problem is best handled with patience and understanding, and lifestyle changes, bladder training, moisture alarms, and sometimes medicine may help lessen bed-wetting.

What are the symptoms of bed-wetting?
The symptom itself is straightforward: your child passes urine while asleep. The timing and pattern tell you more than the wet sheets do.
Most kids are fully toilet trained by age 5, but there is really no target date for having complete bladder control. Between the ages of 5 and 7, bed-wetting remains a problem for some children. After age 7, a small number of children still wet the bed.
When to see a doctor
Most children outgrow bed-wetting on their own, but some need a little help. In other cases, bed-wetting may be a sign of an underlying condition that needs medical attention.
Talk to your child's doctor or other health care professional if your child still wets the bed after age 7, or if your child starts to wet the bed after a few months of being dry at night.
Also seek care if, in addition to wetting the bed, your child has pain when passing urine, is often extra thirsty, has pink or red urine, has hard stools, or snores. These can point to an infection, diabetes, constipation, or sleep apnea that deserves evaluation.
Sign or symptom | What it may point to |
Bed-wetting after age 7 | Nighttime bladder control may still be developing, or an underlying cause may be present |
Wetting again after months of dry nights | A new underlying condition may need attention |
Pain when passing urine | Possible urinary tract infection |
Often extra thirsty | Possible diabetes |
Pink or red urine | Possible urinary tract infection |
Hard stools | Possible constipation |
Snoring | Possible obstructive sleep apnea |
What causes bed-wetting?
Doctors do not know for sure what causes bed-wetting, though a small bladder, a hormone imbalance or an infection may contribute. Several issues may play a role, and they often overlap.
A small bladder. Your child's bladder may not be developed enough to hold all the urine made during the night.
No awareness of a full bladder. If the nerves that control the bladder are slow to mature, a full bladder may not wake your child. This may be especially true if your child is a deep sleeper.
A hormone imbalance. During childhood, some kids do not produce enough anti-diuretic hormone, also called ADH. ADH slows down how much urine is made during the night.
Urinary tract infection. Also called a UTI, this infection can make it hard for your child to control the urge to pass urine. Symptoms may include bed-wetting, daytime accidents, passing urine often, red or pink urine, and pain when passing urine.
Sleep apnea. Sometimes bed-wetting is a sign of obstructive sleep apnea, when a child's breathing is interrupted during sleep. This is often due to swollen and irritated or enlarged tonsils or adenoids. Other symptoms may include snoring and being sleepy during the day.
Diabetes. For a child who is usually dry at night, bed-wetting may be the first sign of diabetes. Other symptoms may include passing large amounts of urine at once, increased thirst, extreme tiredness, and weight loss in spite of a good appetite.
Ongoing constipation. A child who is constipated does not have bowel movements often enough, and the stools may be hard and dry. When constipation is long term, the muscles involved in passing urine and stools may not work well. This can be linked to bed-wetting.
A problem in the urinary tract or nervous system. Rarely, bed-wetting is related to a difference in the structure of the urinary tract or nervous system.
Who is at risk of bed-wetting?
Bed-wetting can affect anyone, but it is twice as common in boys as in girls.
Several factors have been linked with an increased risk. Stressful events may trigger bed-wetting; examples include having a new baby in the family, starting a new school, or sleeping away from home.
Family history matters too. If one or both of a child's parents wet the bed as children, their child has an increased chance of wetting the bed as well. Bed-wetting is also more common in children who have attention-deficit/hyperactivity disorder (ADHD).
Risk factor | How it is linked to bed-wetting |
Being a boy | Twice as common in boys as in girls |
Stress and anxiety | New baby, new school, or sleeping away from home may trigger it |
Family history | Increased chance if one or both parents wet the bed as children |
ADHD | More common in children with attention-deficit/hyperactivity disorder |
What complications can bed-wetting cause?
Although frustrating, bed-wetting without a physical cause does not result in any health risks. But bed-wetting can create some issues for your child.
Guilt and embarrassment can lead to low self-esteem. Children may also lose opportunities for social activities, such as sleepovers and camp. Rashes on your child's bottom and genital area can develop, especially if your child sleeps in wet underwear.
These complications are about comfort and confidence rather than physical harm, and both respond well to patient, shame-free support from parents.
How is bed-wetting diagnosed?
Depending on your child's situation, the health care professional can check for any underlying cause of bed-wetting. A treatment plan can then be made based on what they find.
The evaluation usually includes a physical exam, plus a discussion of symptoms, fluid intake, family history, bowel and bladder habits, and the problems caused by bed-wetting.
Urine tests check for signs of an infection or diabetes. X-rays or other imaging tests of the kidneys or bladder look at the structure of the urinary tract, and other types of urinary tract tests or assessments may be done if needed. You are likely to start with your child's pediatrician, and may be referred to a doctor who specializes in urinary disorders, called a pediatric urologist or pediatric nephrologist.
Diagnostic component | What it covers |
Physical exam | General check for underlying causes |
Symptom discussion | Fluid intake, family history, bowel and bladder habits, problems caused by bed-wetting |
Urine tests | Signs of infection or diabetes |
Imaging tests | X-rays or other imaging of the kidneys or bladder to look at urinary tract structure |
Specialist referral | Pediatric urologist or pediatric nephrologist if needed |
How is bed-wetting treated?
Most children outgrow bed-wetting on their own. If treatment is needed, talk about options with your child's health care professional. Together you can decide what will work best for your child.
If your child is not especially bothered or embarrassed by an occasional wet night, lifestyle changes may work well. These include not having caffeine, limiting liquids in the evening, and passing urine right before bed.
If lifestyle changes are not successful, or if your child is upset or worried about wetting the bed, other treatments may be helpful. If found, underlying causes of bed-wetting, such as constipation or sleep apnea, should be looked into by a health care professional. Options for treating bed-wetting include moisture alarms and medicine.
Moisture alarms
Moisture alarms are small, battery-operated devices that connect to a moisture-sensitive pad on your child's pajamas or bedding. When the pad senses wetness, the alarm goes off. You can buy these moisture alarms without a prescription at most pharmacies.
Ideally, the moisture alarm sounds just as your child begins to pass urine. This should be in time to help your child wake, stop the urine stream, and get to the toilet. If your child is a heavy sleeper, another person may need to listen for the alarm and wake the child.
If you try a moisture alarm, give it plenty of time. It often takes 1 to 3 months to see any type of response, and it may take up to 16 weeks to have dry nights. Moisture alarms are effective for many children. They carry a low risk of side effects and may provide a better long-term solution than medicine does, though these devices may not be covered by insurance.
Medicine
If lifestyle changes do not help your child stay dry, your child may be prescribed medicine for a short period of time to stop bed-wetting. Certain types of medicine can slow how much urine is made at night or calm the bladder.
The drug desmopressin (DDAVP) reduces how much urine is made at night. But drinking too much liquid with the medicine can cause problems. Do not use desmopressin if your child has symptoms such as a fever, diarrhea, or nausea. Be sure to carefully follow instructions for using this medicine.
Desmopressin is an oral tablet. It is only for children 6 years or older. According to the U.S. Food and Drug Administration, nasal spray forms of desmopressin are no longer recommended for treatment of bed-wetting due to the risk of serious side effects.
If your child has a small bladder, an anticholinergic drug such as oxybutynin (Ditropan XL) may help reduce bladder contractions and increase how much urine the bladder can hold. This may be especially helpful if daytime wetting also occurs. This medicine is usually used along with other medicines and is generally only recommended when other treatments have failed.
Sometimes your child may be prescribed more than one type of medicine. But there are no guarantees that medicine will work, and medicine does not cure the problem. Bed-wetting typically starts again when medicine is stopped. This may happen until bed-wetting ends on its own at an age that varies from child to child.
Treatment option | How it works | Key points to know |
Lifestyle changes | Limit evening fluids and caffeine; pass urine right before bed | Good first step if your child is not bothered by occasional wet nights |
Moisture alarms | Battery-operated pad senses wetness and sounds an alarm to wake the child | Available without a prescription; may take 1 to 3 months to respond, up to 16 weeks for dry nights; low side-effect risk; may not be covered by insurance |
Desmopressin (DDAVP) | Oral tablet that slows how much urine is made at night | For children 6 and older; avoid excess fluids; not for use with fever, diarrhea, or nausea; nasal spray no longer recommended |
Oxybutynin (Ditropan XL) | Anticholinergic drug that calms the bladder and increases capacity | Helps if daytime wetting also occurs; usually combined with other medicines; used when other treatments fail |
Treat underlying causes | Constipation or sleep apnea evaluated and treated by a health care professional | Always checked if found during evaluation |
What home habits help with bed-wetting?
Beyond the main treatment options, several changes you can make at home may help with bed-wetting.
Limit fluids in the evening. It is important to get enough fluids, so there is no need to limit how much your child drinks in a day. But encourage drinking liquids in the morning and early afternoon. This may lessen thirst in the evening. Don't limit evening fluids if your child has sports practice or games in the evenings.
Avoid drinks and foods with caffeine. Caffeine is not a good idea for children at any time of day. Because caffeine may stimulate the bladder, it should especially be avoided in the evening.
Urge double voiding before bed. Double voiding is passing urine at the beginning of the bedtime routine and then again just before falling asleep. Remind your child that it is OK to use the toilet during the night if needed. Use small night lights so your child can easily find the way between the bedroom and bathroom.
Urge regular toilet use throughout the day. During the day and evening, suggest that your child pass urine every 2 to 3 hours or so, or at least often enough to avoid a feeling of needing to pass urine right away.
Prevent rashes. To prevent a rash caused by wet underwear, help your child rinse their bottom and genital area every morning. It also may help to cover the affected area with a protective moisture barrier ointment or cream at bedtime. Ask your health care professional for product suggestions.
What about alternative medicine for bed-wetting?
Alternative medicine is a popular name for health care practices that traditionally are not part of well-researched standard medicine. Complementary and integrative medicine, when based on solid research, may sometimes be used along with standard medicine.
Some people may choose to try complementary or alternative medicine approaches to treat bed-wetting. For hypnosis, acupuncture, chiropractic therapy, and herbal therapy, evidence of effectiveness is weak, not conclusive, or proved to not be effective. In some cases, the studies were too small or not done carefully, or both.
Be sure to talk to your child's health care professional before starting any complementary or alternative therapy. If you choose an approach that is not standard, ask if it is safe for your child. Also make sure that it will not interact with any medicines your child may take.
How can parents and children cope with bed-wetting?
Children do not wet the bed to annoy their parents. Try to be patient as you and your child work through the problem together. Effective treatment may include several strategies and may take time to be successful.
Be sensitive to your child's feelings. If your child is stressed or anxious, encourage your child to express those feelings. Offer support and encouragement. When your child feels calm and secure, bed-wetting may become less of a problem. If needed, talk to your child's health care professional about additional strategies for dealing with stress.
Plan for easy cleanup. Put a plastic cover over your child's mattress. Use thick, absorbent underwear at night to help contain the urine. Keep extra bedding and pajamas handy. But avoid the long-term use of diapers or disposable pull-up underwear.
Ask your child to help. If your child is old enough, consider asking your child to rinse wet underwear and pajamas or place these items in a specific container for washing. Taking responsibility for bed-wetting may help your child feel more control over the situation.
Celebrate effort. Praise your child for following the bedtime routine and helping clean up after accidents. Use a sticker reward system if you think this might help motivate your child. Bed-wetting is not done on purpose, so it doesn't make sense to punish or tease your child for wetting the bed. For the same reason, rewarding dry nights is not helpful. Also, discourage siblings from teasing the child who wets the bed.
How do you prepare for your appointment?
You are likely to start by seeing your child's pediatrician or other health care professional. Before your appointment, make a list of any symptoms, including any major ones that may seem unrelated to bed-wetting. Consider keeping a diary of your child's bathroom visits and wet and dry nights. Note when your child goes to the toilet and whether your child felt a need to pass urine right away. Also note how much liquid your child drinks, especially after dinner.
Include key personal information, including any major stresses or recent life changes, and any family history of bed-wetting, including siblings or parents. List all medicines, vitamins, herbs, and other supplements that your child takes, and the doses. Finally, prepare questions to ask your child's health care professional so you can make the most of your time together.
Some basic questions to ask may include: What is causing my child to wet the bed? When might my child outgrow wetting the bed? What treatments are available, and which do you suggest? Are there any side effects? Are there any options other than the main approach that you are suggesting? Should my child limit drinking fluids at certain times? Are there any brochures or other printed material that I can have, and what websites do you recommend?
During the visit, expect your child's health care professional to ask questions too. These commonly cover family history of bed-wetting, whether your child has always wet the bed or it began recently, how often it happens, whether there are dry periods, whether your child is dry during the day, whether your child is having stool accidents, whether your child complains of pain or other symptoms when passing urine, and whether your child is facing any major life changes or other stresses. If you are separated or divorced, expect a question about whether your child alternates living at each parent's home and whether the bed-wetting occurs in both homes. They will also ask how you respond to your child's bed-wetting.
What is the bottom line on bed-wetting?
Bed-wetting is a developmental milestone that some children reach later than others, not a behavioral problem and not a toilet training failure. It affects children twice as often when they are boys, tends to run in families, and shows up more in children with ADHD or recent stress. Before age 7, it generally is not a concern, and most children outgrow it on their own.
That said, it is worth a doctor's attention when bed-wetting continues past age 7, returns after months of dry nights, or arrives with warning signs such as painful urination, pink or red urine, unusual thirst, hard stools, or snoring. These can point to an infection, diabetes, constipation, or sleep apnea that is easy to check for and important to catch early.
The most effective approach is the unhurried one. Evening routines, like limiting late fluids and caffeine and double voiding before bed, handle many cases on their own. Moisture alarms offer a low-risk, longer-term option that works for many children, and short-term medicines such as desmopressin can help when routines are not enough, though they do not cure the problem and bed-wetting usually returns when they stop.
Above all, keep it shame-free. Children never wet the bed on purpose, so punishment and teasing only deepen the embarrassment without changing the outcome. With patient routines, practical cleanup planning, and help from a health care professional when needed, dry nights usually follow in time.
Take the next step: If your child is under 7 and occasionally wets the bed, start a calm evening routine of limited late fluids and a bathroom trip right before sleep, and praise effort rather than dry nights. If your child is 7 or older, is wetting again after a dry stretch, or shows warning signs like painful or discolored urine, unusual thirst, hard stools, or snoring, book a visit with your pediatrician.
FAQ
Is bed-wetting normal after age 5?
Yes. Most kids are fully toilet trained by age 5, but there is no target date for complete bladder control, and bed-wetting remains common between ages 5 and 7. It is generally not a concern before age 7, since nighttime bladder control may still be developing.
Why does my child wet the bed even though he is fully potty trained?
Bed-wetting is not a toilet training problem. It is usually linked to a small bladder, bladder-control nerves that are slow to mature, low night-time anti-diuretic hormone (ADH), or factors like constipation or a urinary tract infection, and deep sleepers may simply not wake to a full bladder.
What helps a child stop wetting the bed at night?
Start with lifestyle changes: limit evening fluids and caffeine, use double voiding before bed, and encourage regular toilet breaks during the day. Moisture alarms work for many children over 1 to 3 months, and a doctor may prescribe a short course of medicine such as desmopressin for children 6 and older when other steps are not enough.
When should I see a doctor about bed-wetting?
See a doctor if your child still wets the bed after age 7, starts wetting again after being dry at night for a few months, or has warning signs like pain when passing urine, often being extra thirsty, pink or red urine, hard stools, or snoring.
Should I punish my child or reward dry nights?
No to both. Bed-wetting is never done on purpose, so punishment and teasing only worsen embarrassment. Rewarding dry nights is also not helpful, since the child cannot control them. Instead, praise effort for following the bedtime routine and helping with cleanup.
Disclaimer: This article is for general informational purposes only and does not constitute medical advice. Always consult a pediatrician or qualified health care provider for individual questions.
Does bed-wetting run in families?
Yes. If one or both parents wet the bed as children, their child has a higher chance of wetting the bed too.
Can constipation cause bed-wetting?
Yes. Long-term constipation can press on the bladder and affect the muscles that control urine. Treating the constipation often helps with bed-wetting.
Can stress cause bed-wetting?
Stressful events, like a new baby, a new school or sleeping away from home, can trigger bed-wetting. Calm support and reassurance usually help more than pressure.
Is desmopressin safe for children who wet the bed?
Desmopressin tablets are used for children 6 and older under a provider's care. Limit drinks around bedtime as directed, and skip the medicine if your child has fever, diarrhea or nausea.
Should my child wear pull-ups at night?
Thick absorbent underwear and a mattress cover can make cleanup easier. Long-term use of diapers or pull-ups is not recommended.
