I have always called "the red man" Father Christmas, and have been calling him that when talking to my 2 dds (4 and 1). However, today we were at a party and everyone kept saying Santa Claus is coming etc, and my two girls didnt have a clue who they were talking about.
I had to try and explain that Father Christmas and Santa Claus were the same man.
Is the trend now to call him Santa Claus or still Father Christmas? I much prefer Father Christmas, but loads seem to use Santa now.
