I imagine it is all about the horrors of Prince Doo-dah kissing SB without a signed letter of consent. Talk about first world problems. I think even small children know that fairy tales are not real.
On the subject of children not being shown things for which their parents have not given permission for them to view, my grown up children laugh helplessly at the following story:-
When I was teaching and they were at a lovely childminders they were allowed to watch a film every so often and took it in turns to pick one. I was very strict about what they could see at home and fought many battles over, for instance, films like 'Jurassic Park' which I forbade but which all their peers had seen.
At the time they gave me 'edited' versions of what they viewed. All wholesome, of course.
Years later they told me that my DS chose 'Jurassic Park', Terminator' and the like (he was nine, she was seven) and she chose 'Cinderella'. Every single time.
I don't know who was more traumatised. My poor girlie hiding behind the sofa at the scary bits or my DS having to see 'Cinderella' fifty times.
I nearly died when they told me years later but they both seem to have survived and they think it is simply hilarious.
I imagine a child might just survive watching Disney's 'Sleeping Beauty'. Maybe they could have a trigger warning and a counselling session afterwards.
