Urination normally works for children and adults, too. The bladder is a balloon-like organ. It stores urine. The bladder muscles contract (squeeze) when we're ready to release urine. But when children have urinary incontinence, they involuntary release urine even after being toiled-trained. It may occur during the day or night. If a child between the ages of 5 and 18 has two or more wetting episodes a month, he or she may benefit from treatment to gain bladder control. Clinically this condition is termed Enuresis.
If your child makes frequent trips to the restroom, wets the bed, or leaks urine involuntarily, it could be a sign of Enuresis.
