Just that really, just wondered how everyone else does Christmas when they have step kids.
DH and I have a toddler DD and he has a DD from previous relationship age 9.
We tend to do a Christmas day out as a family to see santa in the weeks leading up to Christmas, then we always pick up DSD Christmas night and have her for boxing day.
Christmas day we tend to open presents at home with DD and then go to see my family., she will open presents from my family and the presents my family have bought DSD we take home for her to open Christmas night after we pick her up.
Boxing day is Christmas day number two and the kids get up and open their presents (DD has half her presents Christmas day then half boxing day) and then we see DHs family.
Works for us as both children (and adults) get two Christmas days.
