I have always wondered why some celebrate and open presents on Christmas Eve and others on Christmas Day. My husband is from German ancestry and me from Irish. He had to be prodded to even consider opening his presents before Christmas morning. LOL
Growing up we got to open one present on Christmas eve but the rest had to wait until morning. I think my parents just got tired of being hounded and decided to give in and let us open one. heh.
Here's a guilty secret. One year when I was about 9 or 10 or so, I snuck out and unwrapped all my presents in the middle of the night and re-wrapped them all for morning. I evidently had to learn first hand about the value of waiting and anticipation. It wasn't worth it of course because opening them in the morning was so anticlimactic but I was sensitive to my family's feelings and pretended to be all excited anyway.
I did it that one time and never again. Ornery little cuss wasn't I? :^P

When I was little, we always had to wait till Christmas morning, but when I was in my teens, we started opening one present on Christmas Eve after church. I continued the tradition with Dawn and Tyler.
Why not wait until Epiphany (Jan 6 - Twelfth Day) and celebrate that arrival of the Magi? It also has the advantage of making it possible to buy your gifts at the after Christmas sales.
