My 3 year old son started 5 day afternoon preschool in Oct. He has always been very smart and active and he needed more social interaction. His "from birth" qualities seemed to be always on the move, always hungry, trouble sleeping, funny, silly, smart, dare-devil, ENERGY! From the first day of school he talked of a boy that was "mean and hurt him." over the course of weeks his behavior is quickly changing. He is mean and destructive now. He won't share and hurts his 1 year old sister and 10 week baby cousin. He is regressing and while potty trained at 18months he now has accidents everywhere and wets the bed. Last nigth I caught him using his feces for finger paints and in the same night peeing on the couch and rubbing his face in it. He has started saying he is now the "bad boy" and calls himself by the other childs name. The teacher has confirmed there were problems between the boys and notices to that my sons behavior is changing. I don't know what to do... Pull him out of school, see a doctor???? He has always been a lot to handle do to his energy but now its a bad energy unlike his normal self.
