bubble boy

I love my children. LOVE THEM. But lately they drive me crazy!! Where are on earth do they learn such behaviors like hitting one another as though they are golf balls, and biting clothes and trying to drag one another away, and grabbing by the neck and falling backwards? (OK, so its always a certain brother doing the action, and a certain other always crying in reaction.) Why are boys so mean? Where did all this energy and aggresion come from? I thought I put a stop to it when we stopped watching Lion King (that definitely explains the biting).
What are you supposed to do? Ignore it and hope it stops? Try to bribe it with the thought of a treat? Lock it away in the corner in a time out? Cause none of these seem to be a solution. Someone should invent a force field that goes around a child that you can turn on and off with a remote that prevents siblings from being able to make contact. That would sell.
