I disguised the title somewhat just in case there are some kids looking over your shoulder!
I'm wondering at what age your kids - those in families celebrating Christmas and promoting Santa - figured it out. My oldest DD is 9 and has not said anything, but I can tell she is struggling a bit, because, I imagine, her peers are talking about it in school. She wrote her letter to Santa in great secret the other day - if I walked past she would cover the letter with one arm - then sealed it up in an envelope. Since she has said absolutely nothing about what she would like from Santa I was a bit panicked. When she left the room and the envelope was still moist from being recently sealed, I opened the letter and quickly read it, then resealed it. She came into the room later and I saw her pick up the letter and check the seal (you could never have told that it had been opened) and seemingly satisfied, put it down. It was pretty clear to me that she still believes, and wants to believe, but has some doubts. I'm guessing kids at school are telling her "it's your parents" and that this was her was of testing that theory - like, if we didn't see the letter but Santa got the gift correct, then she would be vindicated.
I'm fairly certain at 9.5 that this Christmas will be her last one to believe in Santa Claus. She has a much younger sister and it is my hope that rather than be devastated, she will join me in creating the magic. She is a very unsophisticated kid who has been sheltered thus far from most pop cultural influences and still believes in fairies, etc. I am feeling pretty sad and nostalgic about the whole thing. I know I will savor her belief this Christmas.
I'm curious about when your kids put two and two together? Were they devastated?
