Quoting Rista Kat:" I feel bad now. I don't know if he was mad at me for sorting the laundry and not catering to his needs, or if he was still mad about having to do his chores and getting his motorcycle taken away."
Thats why you need to asak him why he is mad........When my kids were about 3 whenever they got mad or were starting to get mad, I would put music on and let them dance out their anger for a few minutes. When it was done I would ask them why they were mad or angry etc....
After doing it for a about a week they would get angry and go turn it on themselves then come and tell me why they were angry.
It worked for my kids, may not help with other kids. But maybe soemthing simular for futur cases of madness. lol
