What Is It?
Bedwetting, also called nocturnal enuresis, means that a child accidentally passes urine at night during sleep. Because this is normal in infants and very young children, bedwetting is not considered a medical problem unless it happens in a child who is already in elementary school or who was completely dry day and night and then began to wet the bed again during the night.
By age 5, 80% to 85% of children are consistently dry throughout the night. After age 5, the number of children who continue to wet the bed decreases by about 15% per year, even without treatment. Only 1% of children still wet the bed by the time they are 15 years old.
