I have been working for some time with the ticket system, mostly targeting listening to adults. The exception being he loses all tickets for hitting. My son is not responding well. I expected it to get worse before getting better. Now he flies into total rages over almost nothing. He asked me to play with him this morning. When I said no he tipped over the kitchen table and chairs and proceeded to throw everything he could in his room. I then removed his toys and told him he lost his tickets and would have to stay in his room. So he knocked the closet doors off the tracks. Is this normal ? How should I handle this?
