our school not only doesn't allow homemade treats, there are no parties at all with any kinds of treats. the only thing that has ever happened so far is my kids k/1st teacher (they looped) would have something called "party in a bag" at the end of the year, when the kids got to bring in special treats for snack...only they got to eat what was in their bag, but it was as close to a party with treats our school does.
