Let’s remember that they took all of them to see The Meg a few years ago, which is also a 12. They don’t care or monitor what they read/watch.The books are not suitable for Esme at all, I completely agree with you. She has just turned 11! As well as the sex side, there is the obsessive relationship and complete power/domination from a boyfriend. Guarantee Lazy won’t talk to her about any of it. Then again I think Isla is too young for Harry Potter but I know it’s a common one for children her age it seems...
On a slightly separate note, this conversation of suitable book reads reminds me of a couple of years ago when my mum, who’s a teacher, mentioned to me that on World Book Day, one of her 10 year olds brought in 50 Shades of Grey
