We often send alternate foods, but because of diabetes. I do not pay any attention to the daycare menu when I pack snacks/meals. I guess I don't see the need for kid food to 'match' so I just send healthy foods I know the kids will eat. They never share a snack (as the daycare snacks are too many carbs for a snack) so mine will have a pudding or a piece of of fruit or whatever while the kids there are eating crackers, pretzels, etc. And we do milk-free at daycare simply because we do organic only - the daycare doesn't, and I don't feel like providing it daily/weekly. So, mine eat different foods 75% of the time and always drink different things (as we don't do juice either).
