I was thinking about how I learned that my parents were Santa Claus. We were in a store in December on line to the cashier when I asked my mom why our shopping cart was filled with toys. She replied that she was Santa and was paying for the toys.
Please contribute how you learned

As my little kid self sat on Santa's lap in our home, I recognized Santa was my Uncle Charlie. Hmmm. I think that is when I knew.
