I feel so bad for kids whose parents don't have the knowledge and/or care enough to feed their kids well. It will definitely be a battle for you if the parents are not on board with healthy eating. The child fills up on junk and can hold out until he gets home if need be rather than eating the healthy foods you try to offer. One note about juice...it fills kids up and takes space that could be used by foods. I don't serve juice for this reason. Maybe she could have it as a treat ater having eaten some healthy food? WIll she drink a smoothie? If so, one thing I do is make fruit and yogurt smoothies and throw in raw spainch...the kids can't taste it I also load all of my pasta sauces with a ton of veggies and puree it...never had a kid yet who won't eat it I also throw veggies and fruits into all muffins I make or pancakes. Basically, there is no point in giving empty calories, so everything has to have maximum nurtition, especially if the child isn't eating much. Good luck! I had one little girl who ate junk at home and it took a long time for me to get her eating even half the fruits and vegetables I serve.
