I think that perhaps Santa and his elves listen all year long to each child in a family, and when they hear something that a child may like or want, they get busy making it in the workshop. I think that somewhere around the North Pole, the elves store gifts that are finished. Maybe they have individual boxes or shelves for each child, and all year long, they add to each child's pile.
I think that perhaps one of the elves must have a special, secret notebook in which she keeps track of each item for each child. She may even keep track of how much it cost for the elves to build each gift. I'm sure the elves try to keep things equal, don't you think?
Of course, as Christmas gets closer, things get much more hectic at The North Pole. I imagine the elves work very hard during October and November so that by December, all the major work is completed. Once all the gifts are made, the wrapping elves takeover and most likely spend an evening wrapping and storing each child's gifts in a box or bag. They probably put the boxes in a safe place so that on Christmas Eve, they are all ready to load in Santa's sleigh! The elves only need to tie up loose ends during the month of December, and therefore they have more time for enjoying their favorite time of year! I think the elves and Santa probably watch Christmas movies, listen to Christmas music, bake lots of Christmas cookies, and maybe even simply sit by the tree relaxing, knowing that they are all ready for Christmas Day. I am sure they also spend time thinking about the true meaning of Christmas too, don't you think?
When the big night finally arrives, the elves only have to load up the sleigh, and watch as Santa does his magic, placing presents, filling stockings, and eating cookies. Then, I imagine, when he is all finished, Santa takes some time to sit in front of his own tree with Mrs. Clause, and enjoys the quiet, calm night that is the holiest night of the year. And then...he goes to sleep, safe in the knowledge that he and his elves have made each and every child very happy on Christmas Day.
Of course, these are only my thoughts on how Santa and his elves prepare for Christmas. No-one really knows for sure. : )
