Bedwetting, or nocturnal enuresis, is when a child wets the bed at night, more than twice a month, after age 5 or 6.
The last stage of toilet training is staying dry at night. To stay dry at night, your child's brain and bladder must work together so your child wakes up to go to the bathroom. Some children develop this ability later than others.
Bedwetting is very common. Millions of children in the U.S. wet the bed at night. Some children still wet the bed at age 7, or even older. Although the problem usually goes away over time, many children, and even a small number of adults, continue to have bedwetting episodes.
Bedwetting also runs in families. Parents who wet the bed as children are more likely to have children who wet the bed.
There are 2 types of bedwetting.
While less common, physical causes of bedwetting may include:
Remember that your child has no control over bedwetting. So try to be patient. Your child also may feel embarrassed and ashamed about it, so tell your child that many children wet the bed. Let your child know you want to help. Above all, don't punish your child or ignore the problem. Neither approach will help.
Take these steps to help your child overcome bedwetting.
You might also try using a bedwetting alarm. These alarms are small and easy to buy without a prescription. The alarms work by waking children when they start to urinate. Then they can get up and use the bathroom.
You may also want to use a chart or keep a diary that your children can mark each morning they wake up dry. This is especially helpful for children, ages 5 to 8 years old. Diaries allow you to see patterns in your child's habits that may help. You can also show this diary to your child's doctor. Write down:
Always notify your child's doctor of any bedwetting episodes. A child should have a physical exam and a urine test to rule out urinary tract infection or other causes.
Contact your child's doctor right away if your child is having pain with urination, fever, or blood in the urine. These may be signs of an infection that will need treatment.
You should also call your child's doctor:
Your child's doctor may prescribe a medication called DDAVP (desmopressin) to treat bedwetting. It will decrease the amount of urine produced at night. It can be prescribed short-term for sleepovers, or used long-term for months. Some parents find that bedwetting alarms combined with medicine work best. Your child's doctor will work with you to find the right solution for you and your child.
