Feed them first. Be sure your kids go out trick-or-treating with full stomachs to discourage snacking en route.
Consider a swap. Some parents keep natural candies on hand and trade for the unnatural ones. Other parents have a highly desired toy on hand to offer in exchange for the stash. Others tell their young children that if they set their bags of candy outside their door, the Halloween Witch will come by to collect the candy and leave a toy in its place.
Consider a buy-out. Many kids sell their candy back to Mom; it’s a big money-maker for them. (My kids continued going trick-or-treating even after they became teenagers. They were a bit embarrassed to be out with the little kids, but the income was so good they hated to give it up.)
Limit the damage. If you and your child go through the stash and toss out the most brightly colored candies (due to dyes), and eat only a limited number per day, you will probably be able to weather the event.
Consider giving out balloons or trinkets (that are too big to swallow) to the trick-or-treaters who come to your home.
