Elf on the shelf part 2

So I'm 2 weeks in to elf on the shelf and have realised that while my 1 year old thinks it's hilarious and cackles pointing at the elves, my 4 year old is "not impressed" (her own words) when the elves do something remotely messy or untidy. The toothpaste on the mirror got a really unpleasant scowl, and the selfies they took with her when she was sleeping got them both a smack... in half tempted to find antics which I know will annoy her just to see how pissed off she gets... bad mummy! Ah well tomorrow will be a better one as she had a candy cane treasure hunt to go on!
