On the plus side, and it's surprised a long in the tooth sceptic....elves on shelves.
Granddaughters 4 and 8, took them Into town to spend a bit of pocket money. 8yo saw the elf on a shelf....I want one
So they both have one now.
But they love them, even the 8 yo seems to really buy into it, mustn't handle them or they else some of their magic powers , place them carefully at night to see where they are in the morning etc etc.
Tbf, the pleasure they're getting is fantastic....
