I agree that spanking is not the answer! I am not a spanker or a hand slapper at all.
I don't know if he is jealous. As I said, he doesn't do it out of anger...he laughs the whole time. I think if he was jealous, he would try to hit whoever I am playing with at the time, and he doesn't do that. I've tried distracting him, removing him, and telling him we do not hit people. Unfortunately (or fortunately, depending on how you look at it), he is being as persistant as I am.
He is my 3rd child and totally is the boss right now! LOL I never went through this phase with my older children.
STILL LOOKING FOR ADVICE!!!!
