Charley, I love the way your Christmas celebrations sound..I used to attend Midnight Mass occasionally at Christmas Eve, one year I took my children to the local Children's Mass at 6pm on Christmas Eve, where they placed the figure of Baby Jesus into the nativity scene at the front of the altar, my son was only 5 at the time and asked when it was time for Jesus to join us in the church, lol!!
I used to tell my children that we couldn't open any of the gifts beneath the tree until after Father Christmas had spread his magic dust over them when he called on Christmas Eve/Morning, it kept them happy for a few years, lol
