I am pretty sure dd5 has figured it out as she's hesitant when she speaks about Santa. However, we took her to see Arthur Christmas last week - it's a new English movie, I assume it's on in the States? It gives a wonderful account of how the current Santa (there is of course generation after generation of the Claus family...) gets the job done - complete with a ninja elf army and ingenious gadgets. Dd LOVED it.
