My husband and I were talking about this the other day. He said that he was in second or third grade when he stopped believing in Santa. I am the youngest of five and my family wanted to keep the spirit of Christmas alive as long as they could, so I didn't stop believing until I was eleven. I found out the truth from my classmates. My daughter is twelve years old and in seventh grade and she still believes in the jolly old elf. What about you?
I can't remember exact age when I stopped believing but I think it was around 8 or 9. I had an older brother and sister who probably revealed the truth to me earlier than I would have wanted :) I tried to keep the legend alive for my son as long as possible!
