Halloween is secretly a great holiday for communication practice; new routines, unfamiliar faces, and a whole script of social language kids get to try out (some of it for the very first time).
"Trick or treat" is a mini social script
Walking up to a door, saying a phrase, waiting, saying thank you; it's a small, low-stakes rehearsal of a social interaction. For kids working on greetings, requesting, or social language, it's a fun real-world chance to practice.
Let them choose (and describe) their costume
Picking a costume is a great vocabulary and opinion-building exercise; asking why they want to be that character, what that character does, what they'll say if someone asks about it. It's a whole conversation hiding inside a fun decision.
Practice greetings ahead of time
For kids who get overwhelmed by unfamiliar faces at the door, a quick practice round at home (knocking on your own door, saying the phrase, taking the candy, saying thank you) can take a lot of the pressure off the real thing.
For kids who are nonverbal or use AAC
A costume is also a great excuse to program a phrase like "trick or treat" onto a communication device, or to use a card to hand out. It's a wonderful, judgment-free environment for a child to communicate however works best for them;, most neighbors are just happy to see a kid at the door in costume.
However your family does Halloween, it's a nice reminder that communication practice doesn't have to feel like practice. Sometimes it's just candy and a costume.
