Bedwetting (Primary Nocturnal Enuresis)

What Increases Your Risk

A child may inherit the tendency to wet the bed.²

• If both parents wet their beds when they were children, there is a 77% chance that their child also will wet the bed.
• If one parent wet the bed, there is a 43% chance that their child also will wet the bed.
• About 15% of children wet the bed even though neither parent wet the bed as a child.

Children who develop at a slower rate than other children during the first 3 years of life have an increased likelihood of wetting the bed. Boys tend to develop more slowly, so they are more likely than girls to wet the bed.
