On Christmas Eve, after we light the Christmas candle (and say a few prayers for those who need them and those no longer with us), we put out refreshments for Santa and the reindeer. Then DD gets new PJs (well, it's now all of us having started with DD) and a Lush Christmassy bath bomb (usually used Christmas Eve).
Then, for her bedtime story, it's the first annual reading of Twas the night before Christmas. I have loads of Christmas books that we read during December, but that is kept for the 24th.
As my dec's box is QUITE full at this stage, I don't get one every single year. But I do try to get one on every international holiday we are on (I have some from 4 different continents at this stage) and they evoke lovely memories when decorating the tree.
I am currently working on getting a full set of a traditional German grouping for my 2 bros, as they are both engaged (1 getting married next year) - some are cheap while others I have got heirloom type ones, but they each represent something that you wish for a newly married couple on their first Christmas. (Things like Santa, Angel, house, rabbit, fish, flower basket, fruit basket, pinecone - can't remeber the rest). I'll eventually gather a full set for myself too (probably not heirloom ones though).
The year after both events (i.e. cheapskate found them on sale) I got 1 for our wedding and 1 for DD's birth, but both Waterford Crystal that I couldn't justify original price.
