My 6 year old will not poop. It began shortly after my husband s divorce from his previous marraige (he is my stepson). I believe it began as behavioral, but now it s becoming something medical. The abdomen is distended but not firm. His pants are constantly poop-stained, and he smells like poop. He swears and cries that he physically cannot feel it. Isn t that some type of medical condition? Perhaps along with the behavioral? I just don t want it to turn into an impaction or obstruction.
