That's almost exactly the same kind of guidelines we have for our co-op preschool -- except that instead of a peanut restriction, we have a dairy (including casein and whey) restriction. Oh, and we do allow 100% fruit juices now and then.
We each are required to take snack up to 18 times a year, and sometimes it gets hard to come up with new things to take. The kids eat a lot of pretzels and canteloupe.
But, we have a few families who are clamoring for even more restrictive guidelines to dissallow any food which is not organic, whole, and raw. They have not yet answered the question that many of us have about how we are to provide two food groups, since all they will allow are raw fruits and/or vegetables.
If the guidelines become that restrictive, we will probably start looking for a new school. I just simply can't afford the cost of providing enough organic fruits and vegetables for that many children 18 times a year.
