I was looking for something fun and Halloween based and I found this small study.
If you've ever wondered how to give out healthier treats effectively on Halloween without getting your house destroyed, this study looked at close to 300 Trick-or-treaters between ages 3 and 14 to see what would happen if they were offered toy treats instead of candy. It found that children were just as likely to choose toys as candy and there were no gender differences.
The implication of this study is that children will not be disappointed by toy treats on Halloween!
