There was a documentary on Amazon Prime Video called The Reason I jump and there are 2 adults on there who use it. It works for them. I am always open to trying new things because it could be the one that works. I think probably you would need a consistent, skilled therapist but it did interest me on the documentary.

My son's secondary diagnosis when he was younger was CAS (childhood apraxia of speech) and when I did not understand what he was trying to tell me, I asked him to spell the words, either by writing or typing on my iPhone or iPad. He hated his AAC device, unfortunately.

Thank you so much for your feedback, we will definitely look into this more!
