I did wonder about the wheelchair tug of war - at the same time, when a child at school that I've taught has been in a wheelchair, they've been included as much as possible. And if we had a tug of war, they'd be given a safe spot.
I think what a poster here is trying to say wrt disabilities is that treating people equally does not mean treating them the same. The same as able bodied or 'neurotypical' people.
The book is not about this.
There are other children's books about this. It's a very hard concept to get across along side the prevailing approach of inclusion and equal treatment/ opportunities etc - something which I don't actually always agree is right for all children, particularly some children with autism.
I have invisible health conditions and I've found life really hard at times because my body can't do what others' can do.,
But this book is, as I said before, about how we look, the likes we like and the freedom to be who we are and do what we like without thinking our body is wrong.
It's a primer for filters and selfies and the sharing of our photos on social media and then feeling shot that we don't look the same as others or personally prefer certain clothes no one else does, accepting our differences and the differences of others. Not telling them they are wrong and must change.
The girl at secondary school who hates make up. She needs to know that that's ok. The girl who uses make up to hide her perceived 'imperfections,' and feels distressed when she doesn't feel in control of her looks and weight. She's a victim of a perfectionist judgy society. (I say this as that girl)
This is different to a personal experience of disability. And those stories need to be told too, this book isn't about that.
