I wouldn't change her dinner time or not set a place for her. That's kinda rewarding her and she will likely just keep up the unwatned behavior.
I tell my almost 3 year old and almost 5 year old that they do not have to eat what I cooked, but they do have to sit down with me and stay at the table. I don't argue with them, don't even hardly respond if they say they don't like it, don't want to eat anymore, etc. The only rule I have is that they get nothing else to eat that night if they do not eat enough dinner. (I don't make them clean their plate, just make an attempt to eat some of everything).
I used to argue and fight and lose my temper sometimes and all that. Finally I learned just to state the facts and leave it at that. Dinnertime has become more relaxed for me and they don't argue with me nearly as much as before. Now, if I could just get them to sit still!! lol
