In keeping with family tradition, the kids got to open a present on Christmas Eve. It's usually a family oriented gift like a board game or movie.
Then Leon and I send the kids off to bed so we can stuff stockings, wrap presents, and place everything "just so". We also take a few minutes to do any pre-dinner preparations.
This year I overbought for their stockings...and for future reference: books don't fit in our stockings very well. So I had to improvise.
