I do not force my son finish his food. I want him to eat because he wants to and because he feels and understands that he needs to eat. I do not know if it is just me but when I make my son finish his plate, he tends to stay away from the kitchen when its eating time. That is why I just let him eat what he wants to eat and when its time to eat. If he can’t finish his food at least he eat, if he can then very good.
