Santa was like sex education at our place. He wasn't something that was ever discussed. I think I was about 6 when I worked it out.
How old were you when your parents told you about Santa?
I don't recall my parents telling me anything about Santa...I think I eventually figured it out on my own, then enjoyed helping playing Santa for my younger sisters!
Parents never told me, I found out through friends around 8 years old.
They never told me. I remember a couple years ago like a week before Christmas and I was digging around under the tree and one present said To: Autumn From: Santa and it wasn't Christmas eve. :)
My parents didn't, my older brother did, and actually he told me about the Easter Bunny and the Santa logic followed.
5, i guess
