Your child does not need to be a part of the clean plate club. I remember growing up that we always had to finish every single bite on our plate. Just remind them that there is no more food for the rest of the night and it will work! My daughter always says she is full after a few bites. I tell her that there is no more food for the rest of the night and if she is really full she is done. If she is still hungry then she will eat a few more bites. It is not right to force food down your kid's throat if they really aren't hungry anymore.
