Every christmas eve my daughters have a bath and just before they get out a cheeky elf knocks on the door and hands a present to the adult that answers and then runs away. He's so quick the girls don't have a chance to see him. The present is usually a new pair of pjs and a Christmas book for bedtime.
In the past we've had...
The Night Before Christmas
Stickman
Rudy's Windy Christmas
The Christmas Bear.
I'll looking for suggestions on behalf of our Christmas eve elf for this year. Our DDs are 4 and 7.
