I agree .... I would have had a consequence for him too.... I don't take that crap from my own kids I certainly won't take it from someone else's. when this kid throws her food or cup have you tried taking ahold of this little girls hands and in a mean face and a louder then normal voice said "no throwing food " and put the item back and when she tries it again repeat and say it again and louder make sure she knows you mean business. I wouldn't take her down that's probably what she wants. I stopped all my kids from throwing food right away using this method.
