Yeah, Santa Claus, the Easter Bunny, and the Tooth Fairy were all a sort of mini rite-of-passage when I was a kid, with everyone figuring it out at different times. Made us feel a little more grown up, especially among other kids who hadn't figured it out yet. And for some reason I don't remember us spoiling it for them - instead we were in on the secret to make the holiday more fun.
