This is worded so insensitively, I don't even know where to start. But I'll try.
Firstly, it is normal, normal for OP's child and normal for a lot of children. It's not, perhaps, typical of many children, but your use of the word normal suggest any subversion is abnormality - which is a horrible way to talk about a person,
Secondly, a neurodiverse brain is not wrong. It's not broken. It runs differently to neurotypical brains, but it is a fully functioning brain. Being autistic isn't 'having something wrong' with you. It's just operating differently.
Finally, you need to be aware that disabled parents, and disabled parents of disabled children, and parents of disabled children will read your words and it will add to the general narrative around disability that it is wrong, and abnormal. And that's just a fucking depressing thing to have to be exposed to regularly.
Please choose your words a bit more carefully whenever you speak about disability, and maybe don't speak at all, if you have nothing kind or constructive to say.
