K.T.
Seems reasonable. I like how you don't give him the satisfaction of an audience...that's kinda key, to not have reactions.
I think after his second time of throwing, I took the food away and took him out of the high chair. Let him know that dinner was over and he wasn't going to get anymore food. I don't know if he was ready to be done with dinner or not, but if he was playing then in my mind it was like he wasn't wanting to eat anymore anyway. He never starved, that's for sure.
