TIME OUT!!! Putting on a show is a)rewarding them for their behaviour, b)is only adding to the hyper activity and c)will not fix anything. If you do a little research on TV and the brain (please note: I am not one of those people who are against TV, I just use it "wisely" I guess you could say). It actually contributes to hyper activity. It uses a different part of the brain and once "released" it adds to a more hyper active behaviour. What I would do in your situation is take them into the kitchen with you and give them a book (triggers a more relaxed state in the brain) or allow them to sit quietly. If my kids ever got aggressive, it would an immediate time out. There is a difference between angry aggressive and playful aggressive, but because the other children are following, this behaviour should not be rewarded. If they want to wrestle, they can do it outside, but not in the house.
