You may also find, as others stated above, "the parents dont really care what their kid eats as long as its healthy" I found that with ALOT of my families. For a while I had "anal" parents or kids that seems to have "tummy issues" so I would write on a dry erase board what we had for the day, just to help inform the parent, if there were issues later in the night, but even then, the meals were not "pre-planned" just wrote down what they had after the meal was served to help inform the parents.
