I have no intention of telling my DS. He definitely believes, after all Santa called him last year and knew everything about him including all his cousins names
I don't remember my parents telling us. We just figured it out.
When I was in college my father asked me to get something out of his sock drawer, not sure why I had never been in their in my childhood, but anyway, inside the drawer was a broken toy of mine. When I was really young I had a toy named "Squeakles" He was a plastic squeaky mouse I received as a baby. I LOVED this toy. He broke when I was 3 or so and my parents told me Santa could fix him. Sure enough Squeakles was all fixed and under the tree that Christmas. I thought it was so sweet that my father kept the original Squeakles all those years. I now have him in my house. The funny thing is the replacement Squeakles was only about 1/2 the size.

. Kids aren't dumb, they just want to believe.
I loved believing as child and as an adult i still believe in the spirit of Christmas.
One year in college I was having a particularly stressful time studying for exams so I found a site and wrote a letter to Santa. I got back the most wonderful personal letter from Santa. I wish I had printed it out b/c I can't access my old college email and I don't remember much about the letter except how wonderful it made me feel that Santa had taken the time to write such a touching, personalized and thoughtful letter to a 20 year old girl. I still smile thinking about it.
OP, I don't think you ever have to break the news to anyone. I don't have a single friend who was angry with their parents when they grew up. It makes no sense. I wasn't mad at my elementary school teachers when I found out Columbus didn't discover America.
