Most people feel that a daily stool is a sign of good health at any age. Some people pay close attention to the frequency, size, and consistency of their children’s stools. Any deviation from the expected norm is a source of concern and leads to a call or visit to the doctor’s office. About 3% of visits to the pediatrician’s office, and 25% of pediatric gastroenterology specialist visits, are for constipation. Functional fecal retention is the most common cause of childhood constipation.
