Hi Sherrad, I didn't realise that you too have a non talker. My son Ciaran didn't speak ( his elder sister spoke for him) until he was 5 or 6 years old. He's on the lighter end of the autistic specturm, so much so that most people would not notice anything unusual about him, except that he can ocasionally suffer form sensory overload in crowds and has a maths obsession and acan obsess over odd things occasionally, but all to such a slight extent that to an outisder it's entirely unnoticeable. We went down the speech therapy route etc and found it to be pretty frustrtaing, and health visiotrs are a patronising nightmare, so I'd entirely disregard them if I were you, as we found them to be a total waste of time. One to one is certainly the answer, and he's now perfectly understandable to the vast majority of people, and suddenly seemed to pick up and run with the idea of talking rather than signing or speaking through his sister. I am sure everything will be well with your little one, and as his mother you will know best, so don't be pushed into a method that you're unhappy with, but for us one to one was definately the answer so I think you're on the right track.
