Teal pumpkins exists so that kids know which homes to skip during trick or treat. It’s great that people want to include kids who can’t eat candy, but it also gives a heads up to those who don’t want to waste their time. There are better things to do and more full size candy bars to find. If my child was allergic to candy then we wouldn’t participate at all. It would be a relief that we didn’t have to walk the neighbor filled with displays of murder and satanism.
