INteresting... (our school uses the middle line paper for their 'handwriting' books. it really helps)
mess yeah, he developed them over about 2years, (we started signing with him when he was just under 2, [he had the same 7 spoken words from about 14 months to over 4] he was purely receptive for about the first 6 months, and then started to produce.. he was upto 3 and 4 sign 'sentences' by the time he was 4. We always used SSE (Sign supported English, so BSL signs but english word order and grammar, and we spoke at the same time.)
I am fluent, so just signed everything I said, and he picked up the signs he wanted/needed. (altho I was using short clear sentences only).
I just wanted to give him a method to communicate, but actually I think it benefitted him in other ways, using sign language means you have to look at the person who is 'talking', and I think he is more NT in this than he would have been without this... You are also using facial expression and body movement to emphasise emotion, which makes it easier to 'read' what someone is feeling.
moondog I am happy to discuss the professionals responses,(crappy as they were!) they fell into two catagories, basic ignorance; "signing slows aquisition of speech", "signing does not work with children with ASD, as it is transitory" and faux professional. "we don't use SSE, we use Signalong". Really funny thing is when I tounge in cheek asked them for the evidence behind the choice of signalong, as (of course)
they must have made that decision on the basis of evidence of outcomes for kids like ds...??? it never arrived, but they stopped insisting we change what was clearly working for ds. (I knew they used signalong instead of makaton because it was cheaper, and they didn't expect kids like ds to be capable of using more complex signing systems like SSE).
Sorry huge post
