I have a 3 yr old boy who most of the time is an angel, other times he is a little monster. He screams, bites, scratches his sister, hits things etc and I do not know what to do. My husband works away I dont really have a support network thingy and its the school holidays, Im stressed so much that Im seeing a cardiologist. Im at tyhe end of my tether I know its probably all "normal" behaviour but Im not coping very well so any ideas and tips would be very much appreciated. :)
