Nocturnalenuresis, commonly called bedwetting, is involuntary urination while asleep after the age at which bladder control usually occurs. Bedwetting is a common problem in kids, especially children under the 6 years old. About 13% of 6-year-olds wet the bed, while about 5% of 10-year-olds do.

Bedwetting often runs in families: many kids who wet the bed have a relative who did, too. If both parents wet the bed when they were young, it’s very likely that their child will.Persistent bedwetting beyond the age of three or four rarely signals a kidney or bladder problem. Bedwetting may sometimes be related to a sleep disorder. In most cases, it is due to the development of the child’s bladder control being slower than normal. Bedwetting may also be the result of the child’s tensions and emotions that require attention.
