See I'm a bit torn. My dd has ASD (see huge other thread). She would point blank refuse to be a 'princess'.
Last superhero day she dressed up as her name, I will out myself if I give the name
So it was almost like I'm going as 'jane' I'm a superhero, she just wore normal clothes, the year before she went as 'qudditch wolf'. Wearing a quidditch cloak and a wolf mask. And at world book day she went as 'all the cats in books' by wearing cat ear muffs.
I'm not attention seeking by going along with it, I'm avoiding a meltdown.
Have you seen the other meme 'in a world of kardashian be amy schumer'
Maybe the parents were trying to create their own 'meme' well they succeeded.
