Most children begin to stay dry at night around three years of age.
Physicians stress that enuresis is not a disease, but a symptom, and a fairly common one. Occasional accidents may occur, particularly when the child is ill. 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.
