Celiac.com 08/24/2018 - Last year was our first gluten-free Halloween and my older son, James (now in 5th grade) got really upset when he realized that he wouldn’t be able to eat a lot of the candy from trick or treat night. He was saying he didn’t want to trick or treat and for awhile wouldn’t pick out a costume. (Prior to this, he loved dressing up and trick-or-treating.)
We solved this problem by having an unsafe candy auction for both of our boys, at the end of the evening. I went out and bought individual candies that I knew they liked (as opposed to bags of it) and non-food treats (small toys, sillybanz - stuff you might put in their stocking at Christmas). When they came home from trick-or-treating, we emptied their bags and divided the candy up: safe pile and unsafe or questionable pile.
(My husband took the bag of unsafe candies to work where he was VERY popular.) At the end of the auction, I had something a little bigger, I can’t remember what it was (maybe a ds game?) The “payment” for the last, big treat was the rest of their unsafe candy.
I hope this helps you as Halloween approaches. My kids loved it and No-one cried.
