Telling Kids About Santa

My oldest is in 6th grade and will turn 12 in a few weeks. She still believes in Santa to some extent though when I talk about Santa with the younger kids, she gets kind of a smirk on her face. However, she still talks about him coming and having to make cookies for him. I take that to mean that she's not ready to admit that he's not real yet.

My husband asked me today if we should tell her because she was getting old enough to know and he didn't want classmates making fun of her. So, we are discussing it and might let the cat out of the bag for our eldest child together.
