We usually give to everyone. I know one year I had a friend who had to send her son trick or treating with no costume because they couldn't afford one so I always try to think of it like that maybe the kids' parents can't afford one..
but yeah I always give the same amount to all ages..We only got like 2 trick or treaters last night and one of them was my little cousin. so we have ALOT of candy left lol..

Since no kids were out trick or treating, I was almost attempted to dress up and go out lol!
