It's interesting to me to hear other parents talk about it. I can't relate to it at all. I also thought that Christmas was amazing, and exciting, and all of that, but without the involvement of some strange fatty sneaking around my house at night.
I teach my kids that Santa is just a fun tradition, not real. Every year we go over the whole bit about some people (especially some of their cousins) are taught to believe that Santa is real, so under NO circumstances they should they attempt to correct other kids on this point.
