I have a dcg who doesn't want to eat veggies/fruit. As I am serving snack/lunch she will say" xxxx no want fruit/veggie". I just ignore her, give everyone else their portion and wait. She sees everyone else eat and she is left out so then she will ask for her portion. When she eats it I tell her she is a big girl and I will let mom/dad know she ate her veggie/fruit and then I do.
