We're a mixed family - dh baptised but non-religious (can't pin him down to agnosticism or atheism, but he definitely does not consider himself Christian), me Jewish, children Jewish - and part of our compromise is to celebrate Christmas in a non-religious way. Last year we did stockings for the first time, dh's POV was that Father Christmas was just an excuse to give more pressies. Now, for teh first time, ds is asking who Father Christmas is, and what Christmas is about.
Anyone in a similar situation? What do you tell your children?
