Every year since they were born, each child has been given a Christmas Book. The idea is that when they are grown and ready to start their own families, these books will be the start of their own Christmas libary. We also get books for our family Christmas Library every so often (not really intentionally, just when I come across a book I want or someone gives us one).
We’ve started to get a respectable collection of books. We keep them put away with the other Christmas things, but when it’s time, they come out and go on a special book shelf for the Christmas season.
