My son is 8 and has had problems for the past 2.5 years with pooping on the potty. We have been to gastro. doctors who said there is nothing physically wrong with him and he has gone to numerous psychologists (which have not helped). He constantly goes in his underwear and when I tell him to sit on the toilet and try he refuses and we end up screaming at each other. I don't know what to do!! He is going in his underwear and then its going thru his shorts and I know that has to be embarassing. We do enemas and he will go right after that, but thats the last time he sits on the toilet. If someone could please help me I would appreciate it soooooo much!!!
