I went to the Spastics Society of India (SSI) recently, and found them in the middle of something new.
They are trying to bring disabled children into the mainstream.
They're working in six Mumbai slums, trying to figure out what it takes to put children with disabilities into existing Government education programmes. That way, these children will not be marginalised, segregated and ignored, they will stop being "Invisible Children".
It's an ambitious effort, to say the least.
But Mumbai has a long history of aware citizens making a big difference, and SSI has the dedication and the professionalism to make this happen.
