Who is affected by bed-wetting (nocturnal enuresis)

Bed-wetting is most common in younger children and is a normal part of developing bladder control until about age 5 or 6. The number of children who wet the bed decreases with age.

About 10% (7% boys, 3% girls) of 5-year-old children wet the bed.1 From age 5 on, about 15% of children who wet the bed become dry each year.2 By age 18 years, bed-wetting is extremely rare in females and is estimated to occur in about 1% of males.1
