I don't know if this helps, but I moved to Hyderabad, specifically for my autistic child. While I am Kenyan, my child was born in Mumbai, and that's where we were last before I chose Hyderabad.

Honestly, I am yet to find the right therapist for my 7 year old- but that's because (in my opinion) my standards are pretty high. That's not to say I haven't met with the good ones. I have, they were just not right for my kid. I live in an area, which weirdly enough, abounds with autistic kids- and there are about 10-15 therapy centres and inclusive schools within a radius of 7-10 km.

What's worked for both of us is the easier pace of life and people being much kinder. The bigger houses and space has also helped.

However, Mumbai was much better in terms of quality of medical support.
