Halloween should be fun, so even though collecting 5 pounds of mass-market, chemical-laden, tooth-decay materials isn’t the greatest idea for a child, it would take a certain kind of mean parent to say NO to all that.
Luckily, there’s a way to let your child go trick-or-treating, and let them enjoy the fruit of their labor* without the feeling that you’re betraying your values just to not rock the boat:
The Switch Witch!
The Switch Witch is the Tooth Faerie’s mischievous sister. She goes to random houses on Halloween night, after children are asleep. She steals all their candy (except what they already ate that night) and switches it for cash! How much? Enough that your kids won’t be upset that their candy is gone. It’s going to depend on their age and how much experience they have with estimating the value of goods.
What you—I mean The Switch Witch—does with the candy after that is up to you…
* Knocking on a stranger’s door can be very difficult for a child, so to them, they’re working hard.
