We did everything just the way we would have done it on the actual Christmas Eve and Christmas Day. On our Christmas Eve we baked gingerbread cookies for Santa, set out the cookies a milk for Santa, and then read The Night Before Christmas and The Christmas Story before putting the kids to bed.
Santa was up very late this year getting all of Aiden and Jenny's toys set up and their presents wrapped ( next year, remind me to wrap gifts a few days before Christmas Eve!). At our house Santa doesn't wrap gifts - he brings them unwrapped, opened, and already put together and ready to play with. Any gifts at our house that are wrapped are from Jaime and I, or from someone other than Santa. That's how it worked when I was growing up, so that's how we do it now with our kids. Something new we started this year, was having Santa only bring 3 gifts each - the same amount of gifts Jesus was brought when He was born. :)
