Now, my four year old knows Santa Claus isn't real. My husband and I decided long before we brought our daughter home that we weren't doing Santa, Tooth Goblin, Easter Bunny, etc. We love Christmas though, it's our favourite holiday and we go all out for it. However, we don't do Santa. My four year old knows this. However, as it approaches the holidays, we worry that she'll blurt it out to other kids at her play-group. We've tried to do our best explaining that some kids do believe in Santa Claus and it's best not to tell them, and I trust she'll do her best, but I do worry that it'll come up in conversation one of these days. She's a very honest kid, she doesn't lie, so I'm concerned if someone asks her she'll just blurt it out. We've been trying to teach her to field the question or simply say "I don't believe in Santa Claus" and leave it at that, but...*sigh*, I still don't know how to explain it so she'll get a decent understanding of it.
