I just received the book, "More Than Words" by Fern Sussman. It was recommended by the folks at Yale, our SLP, and a few books and websites we researched. Prior to going to Yale, I had already looked into purchasing the book.
Its basis is to help parents promote communication and social skills in children with ASD. Only through page 18 so far. They recommend to read the book in its entirety first, which I plan to do. Thumbing through the book, I notice it gives lots of practical suggestions and explains the underlying concepts along with the pragmatics.
But can I get Zach to say "ho ho ho" by Christmas?
