Never taught my daughter about Santa as we celebrate Christmas starting with Advent & through Epiphny....but my inlaws hated that our daughter didn't believe in santa. They always had a Christmas eve party that we went to after going to our Christmas Eve service at church. My SIL knew a lot of stunt people & people from the movie industry as her BF was a stunt man. They arranged for someone to come to the door dressed as Santa.....(for the other little kids there too) & intentionally had our daughter answer the door (she might have been 4 or 5). She looked at him.....said Santa as we told her the original story of who St. Nicholas was & did & she saw Santas in the malls. Anyway she closed the door on him & came back & told them who was at the door. It was a fun evening for all the kids there & it didn't bother me that they did this....gave the kids some fun at kinda an adult party.
