Homemade valentines. We are not allowed to give candy, which I have absolutely no problem with. Ds still has Halloween candy! I'm sure he'll still be getting some though, every where you go you encounter people who are sure the rules don't mean them!
If I don't have to work, I'll be there for the party. Even if I do work, though, I am sending in cheese bites with Valentine picks (hot glue a valentine foamy to toothpicks - keep the paper backing on - really quick and makes a nice presentation) and crackers for the kids. We are encouraged to bring healthy treats, so the rice crispie hearts I was going to bring are a no-go (corn syrup). I was going to make them with honey and peanut butter, but I have no idea if anyone is allergic or not - I'm thinking not, but these days, peanut butter - even outside the poisioning thing - is not something I'd ever bring to school anyway.
