It is that easy - autism therapy

I am been trying to work out how to sum up my mad scientist thoughts - I think I have it.

The one and only difference between an autistic person and a NT person at the beginning stages is the enjoyment of looking at faces. That is it - That enjoyment leads on to learning to talk, imitate etc

Link the enjoyment factor back up to sound and watch.
This is one of many apps (And it is free that will do that)

Sounds too simple doesn't it?  Well it is.  Sorry I have read all the research , I have heard some whoppers from "experts".  It all boils down to this.  This is the only constant at least for children born autistic.
