My kid was fine until he spent a month over his dads house he could use the restroom by himself and he was so active.Now he poops his pants and talks to himself normally and then in a whisper and also has burns on his cheek that were not there before.His speech is so broken he sounds like a robot. He can't even tell me what happens you know as far as explaining himself I don't know what they did to my son.Please help me?
