I believed. But one christmas I found my parents playing the roll of santa and it was gone from there....I think i was about 6 years old.

In my opinion....let 'em believe...it's not like they'll believe in that stuff the rest of their life. they'll find out eventually. as for wanting their kids to know the presents were from them is odd, because little kids can't comprehend such meanings as giving and care and kindness. whats even the point
