Allison,

Have you tried combining music with Facilitated Communication with your son? We use FC at the center I work in. The Speach Pathologists are very supportive of the notion as is Doug Bickland at Syracuse University where considerable research has been done in FC. As well as considerable controversy generated there in. My opinion is I have seen it work and I have seen it not work. Which leads me to think it works for some and not others. (A staggering conclusion I know.) But if 10% of all who try FC find it a benefit then it may be another step in understanding the riddle of autism.

I don't know how to incorporate Music with Facilitation but the research may payoff.
