Of course, this leads to the question, “Should you tell your kids about Santa?” My beautiful wife and I have been talking about this sometimes controversial topic and do want to tell our kids about Santa, in the sense that there is a Santa. We also want to frame that with the story of how Santa was Saint Nicholas.

My cousin and her husband told their eldest son that Santa “wasn’t real” when he was around Kindergarden and he went to school and told all the other kids. We’d like to avoid that. We’d also like to avoid feeling like we’re “lying” to our kid! After all, the reason we have Christmas is not Santa Claus, but is Christ, and certainly want that to be the main focus of Christmas-time in our house. We also don’t want our kid feeling left out because we didn’t tell her the myth of Santa.

I’d love to hear some of what others do with their kids or think is a good idea regarding Santa :-).
