I've been on the fence about having DS believe in Santa. I still have another year or two to really decide. I don't recall being upset with my parents when I learned that Santa was not real, but our babysitter didn't tell her kids Santa was real and put presents out early, so we figured it out pretty quick.

Anyone pick an age to break the news, rather than having their kids figure it out on their own and be mad? Is there a good response if they are really upset about it?
