Father Christmas (as we know him, a person in a red suit bringing gifts to children with reindeer) has been around since the 1840s.
Elf on the Shelf. An elf watching you and reporting on your behaviour, has been around since 2005.
So it's time for some new ideas. Just something magical for children to believe in at Christmas. No idea too outrageous.
I'm going for a magic woodcutter who cuts down a small tree and brings it to your house when the children are asleep. In the morning, it appears in a special container. He does this as he knows that a tree symbolises eternal life and he wants everyone to have one so they can decorate it in a house.
Parents are still free to buy their own tree of course.
