A parent inquires about their nine-year-old child who has been frequently defecating in their pants since the age of eight, with the frequency increasing recently. The parent has already taken the child to medical check-ups for gastrointestinal function and intelligence levels, with no abnormalities found. Despite multiple communications with the child and even resorting to corporal punishment, the child’s behavior has not improved. The parent’s friends suggest that it may be a psychological issue, and the parent wants to know if this behavior could be caused by psychological problems and whether it is normal for the child to lack shame for this behavior.
