My family has lots of Christmas traditions for the days leading up to the big day, whereas Jonathon's mostly keeps it low-key. I tend to LOVE all the traditions and stuff to do: we go watch The Nutcracker ballet in the city, we pick out a real Christmas tree the weekend after Thanksgiving, we decorate cookies, we sleep "under" the Christmas tree on the night of the 23rd (just in the same room, in sleeping bags), we put on the Nativity play on Christmas Eve, followed by a musical program, etc., etc. I think it helps keep the kids busy and happy as they wait for Christmas to come.
On New Year's, though, I know I'd be too tired to do anything more than watch movies and play games. Maybe it's just what you grew up with that you're attached too.
That said, I grew up with BIG Christmas breakfasts involving eggs, bacon, sausage, hash browns, cinnamon rolls, hot chocolate, juice, and mandarin oranges. It just seemed so stressful. I am now very attached to Jonathon's family's tradition of aebelskivers (not terribly difficult to make) and bacon, with juice. Nice enough to be special without taking forever to get on the table and clean up afterward.
