Halloween is just around the corner, and there's an innovative way to let people know that not all trick-or-treaters are the same.

Halloween can be frightening and a challenge for children who have autism. The autism community is using blue pumpkins as a way to let the community know if a trick-or-treater may not be able to speak.

“Say ‘Hello,' even if he doesn't respond back. Sometimes the community doesn't really  know how to interact with my son, you know, and believe it or not, he understands a lot, so just saying hello to him - even if he doesn't give you...that response that you're expecting, do it anyway. It will make the mom real happy,” says Alison Giangregorio, of Long Island.
