I have parents send snacks and lunches also. When I first started it was very difficult to make a meal and snack that all 7 children liked. I find when the parents send the food they know what their child likes and I send back what is left. They can then regulate what they are eating and guage dinner accordingly. When children eye other's treats, I suggest that they mention it to their parents that they would like to try that treat and that their parents will make the final decision as to what is the best for them. By having the parents supply the food it gives me more time to spend offering the parents the extras that they expect.
