My family is quite large (I am one of 5 kids) & we are spread far & wide. My husband's family is much smaller, but again they do not live close, so our Christmases are significant in that there is very little tradition - each year is quite different, depending on where we are celebrating. Last year we had Christmas in Bali, Indonesia with my Mum & sister's family, so that was very different. This year we are celebrating at our home, so it is the first time in years that I have actually put up the Christmas tree!
The only true tradition that seems to continue on regardless is my son's Advent Calendar - it was handmade by his grandmother when he was 2yo with different cross-stitched designs for each day. There are also little cloth bags to hold goodies that he opens every day. Even though he is now 14, this is one tradition that he really enjoys from year to year, regardless of where we are celebrating. The contents of the bags have changed over the years though - he is now getting cash & candy in the bags rather than tiny little toys!
