Holiday traditions for the non-religious?

One of my New Year resolutions is to start some holiday traditions next year that we can continue as River grows. We had decided we’d substitute New Years for Christmas as our main family celebration. Year one, when River was just a few weeks old, we went to a bed and breakfast, which was not very exciting. Year two we visited my family and joined in their Christmas traditions. Year three it’s the same. Next year I’d like to institute some rituals that are ours and that can be continued. Mark baked gingerbread cookies with River and perhaps that could be a regular occurrence. I liked the holiday light appreciation card idea.

Any other suggestions for traditions we could implement that would make the holiday season special and memorable for a kid who is not going to receive piles of gifts on Christmas?
