I think there is an aspect that thinking around disability in general has been changed over the last 20 years.
I have a dd who is nearly 20yo who with a physical disability, and I've seen a of a change in attitude over that time. Some of it is positive, but I'm not sure it is totally.
When she was born I found the attitude was much quieter around it. The children got on and almost always did what "normal" children did. If they didn't manage though, there wasn't much help available.
Now I see blogs/news with "this amazing child who has done XYZ" and I'm more bemused that they thought they wouldn't do it than anything else because all the children I knew did it without more than a minor hiccup.
But the other way too. When there's things they will struggle to do, if anyone says that, then there's great indignation that they should be able to do anything and everything and an aspect of thinking if money is thrown (normally other people's) at it, then it can be solved. Or if it isn't then everyone else should adjust to them.
Unfortunately there are some things that this group of children will find very difficult and will struggle to compete/achieve at the same level as their peers who don't have this disability. That's why we have things like the Paralympics.
It is positive in that there is more assistance available. On the whole children don't get excluded from an activity because it's assumed they can't, and parents and teachers take the line of how can we make sure everyone is included rather than "just sit down quietly over there and don't make a fuss, dear". And if they do try that, then there are lines of complaint that should take it seriously.
Children are more inclined to accept difference and it's great that on TV we see more inclusivity, and children do get very excited at seeing someone "like me" and it boosts their self esteem.
But I'm not sure the attitude of "isn't it amazing" is always helpful. My dd commented one time that she found it far more insulting that they thought she wouldn't manage something than nice to be praised, for example.
I have seen recently someone describing dd's disability as a "superpower". It isn't. It really isn't. It seems amazing to anyone who hasn't got it that she can do some things, but to her it's just as normal as your body is to you. And it does cause problems, both directly due to her disability, and in later life when I can confidently tell you which parts of her body are going to wear out sooner due to overwork.
It does mean she has done things that her siblings haven't. Her disability has given her some opportunities that most children don't get. It still isn't a superpower, and those opportunities don't compensate for what she's missing.
