We just adopted less than 10 days ago, DD is 2, she didn't know anything about Christmas, Santa, Presents, nothing... I did a super crash course teaching her Santa and Christmas, lots of Christmas movies, took her to see Santa, she spent a LONG time with Santa. We told her Santa would bring her lots of presents. Then on Christmas eve we told her to go to sleep and in the morning Santa would have presents for her under the "Christmas" (that's the tree) So when she woke up, we told her, Santa came, which she thought that Santa was actually here, again she really liked Santa. But instead she saw presents and she kept saying, Santa got me lots of presents. She spent about 90 minutes opening presents.
