When did your kids stop believing in Santa Claus? We have 5 kids, 4 of which are now in college. Our 8 year old daughter is still a true believer. It is always so precious watching her excitement on Christmas morning. Watching the old Christmas shows with her like Rudolph, Frosty, Santa Claus is Coming to Town and Charlie Brown Christmas bring back so many great childhood memories. My wife and I sure hope we have a few more years Of Santa Claus.
