I am guessing you mean the children.

I've suggested in a few posts that you have an opportunity to start a new tradition. When my children were young and it was their dad's turn to have them, we would do Christmas on Yule (the 21st of Dec). I'm of celtic and scandinavian background so this just happened to work with old cultural traditions but maybe you could make it part of yours?

ANother idea is to celebrate Orthodox Christmas. Much of the world Christmas day falls on 7 Jan.
