My son just turned 4 and has been having temper tantrums for awhile now. It has gotten much much worse in the past few months. If my son is told that he can't have his way he does everything possible to show his aggresion. Biting, throwing toys, hitting, kicking, screaming. It's incredibly frustrating for me as a single parent to deal with. It has gotten to the point where i have to avoid parties, restaurant, malls. I have friends and family that have children all around his age and none of their children behave this way. When it comes to discipline nothing works with him, punishment will just escalate the problem for us. He grows more and more angry, I have had bruises, scratches and even bloody lips due to his behavior. I'm at my wits end trying to deal with him. I don't think that it is ADD or ADHD because he is able to sit through a movie and long car rides. Does this sound like a psychological issue? Should i take my son to a child psycologist?
