Most of my guys eat what I provide. I have one little girl who is on a very strict diet at home so her parents provide her snack. She is only part time afternoons so its only one snack. I don't change my rate though, same price even though they bring the food. Its worked out ok, she has her snack while the others have theirs and nobody really questions anything. The only time it was an issue was when we do treats for bday's like cupcakes. She can't have them, so one those days I just send the treats home with all the kids and they have them there. Not sure I would want to do it with all 5 kids having different foods, but I like to be as flexible as possible and there are so many issues with food nowadays that if it makes a parent happy to send it, then by all means send away
