My kiddo still believes, he just turned 10. Though he questions me all the time on it, and watched for my reaction. It is actually a little frustrating, he knows I can't afford to get him some of the things he wants (laptop, gaming computer, etc) so he says he will ask Santa for them. I have remembered to move the elf every night, but I am hoping this is the last year. Santa doesn't wrap presents here and he has fewer than usual from Santa this year, because Santa brings toys, not electronic devices. And he is apparently too old for toys. Any way. For me, I was told in kindergarten but some other child in the class who stood up and told us all, there were some mad parents! I still got gifts though so I guess it didn't matter too much
