Agree with the traditions - I think it is those that make Xmas special. We have loads in our family, and Xmas has always been a magical time for us. Some of these traditions may be a bit old for your DD at the mo, but for future years.
When the tree goes up, at least one present per person goes under it. Each day, the person gets to rattle, sniff, shake, listen to and smell the present to guess what it is. Each day, they get one guess as to what that present might be. If they guess correctly, they get to open the present there and then. If they guess wrong, it stays wrapped under the tree for the next day. Obviously, presents are disguised in all manner of forms - shirts inside lemonade bottles and so on... In 30 odd years of guessing, I have never got a present right yet - but I remember the excitement to trying to guess each day, and the fun of thinking up new and barmier disguises each year!
Another tradition we have from when I was younger, was that one present would be wrapped up, and wrapped up loads and in between the layers would be clues to help you guess the present. You were not allowed to get the present until you had guessed what it was - sometimes we would spend all day pondering my dad's bizarre clues. Sometimes there was the real present and a dummy present, and we had to guess which present we wanted - the other present would be saved until the evening, so you hoped you got the 'proper' present instead of the dummy present. That was always fun (And still is, we still do that one!)
Other traditions we had were -
*Obviously making the paper chains and putting up the decs - you can make that into a real family event with Christmassy music, chocolates, or perhaps a film, whatever.
*The big wrapping session before Christmas. I remember from quite young we'd put the Christmas music on, get the Christmas treats out and we would all sit round wrapping up the presents and I would help from quite a young age. I always loved doing this, because it was the weekend before Christmas, and it always meant that Christmas was close!
- The panto is always a good tradition of course..
Hope some of these help. I think often its the way you do things - like wrapping up the presents is not normally a big thing, but because it has become a bit of a tradition, it is for my eldest DD who loves to help and join in with the mince pies and so on...
