I also look at it with the idea I serve one meal and parents serve two. Even if my meal was the worst nutrition they should be eating enough food at home to compensate and balance out. From that standpoint I really do not stress it. A happy mix between what they should eat and what they will eat just works and I compost the rest - noodles they will eat on a day the meat is something they might not for example.

This is where not having your own kids in the daycare works because I am not having to worry that my child might not be eating the best during daycare hours.
