The Switch Witch is a wonderful option to deal with all that candy. But then what do you do with all the candy that "you" (The Switch Witch) have now switched? You shouldn't eat it either.
Try Trick or Treating for UNICEF
A program that has been around since the 1950's, it is a great way to cut down on the amount of candy that your kids are exposed to/given in the course of not just Halloween night, but all the parties and events. They can leave the box with donations out for The Seitch. Witch and she can still switch it as a reward for their hard work!
