This year instead of candy, I found bags of little boxes of stickers and temporary tattoos that I'm going to give out. The kids will probably be just as happy with those and I don't have to feel bad about contributing to the neighborhood kids' sugar addictions.
As for my kids, I've already told them that they will be allowed to eat (within reason) as many as they want that night and then 1-2 pieces a day (as dessert, they're not allowed to bring it to school) until Thanksgiving when whatever is left is going in the trash. No more hanging on to Halloween candy until well past Valentine's day.
I like the idea of that Halloween Fairy, though....the girls might be willing to give up their stash of mostly cheap candy for a new Barbie or Bratz doll.
