x2boys ds has had SALT since he was 10 months old, because of swallowing issues and poor oro motor skills, and we have been learning Makaton since then (not formally, but using books, dvds and just picking it up from SN nursery). We always say the word as we sign, and I help ds to do the sign using hand over hand, he has just starting signing a bit spontaneously to us (he is 2.6). I think my heart would break in 2 if he started to speak, but he has a probable diagnosis of a rare genetic disorder, and many of the children with this disorder remain non-verbal, or have very limited expressive language. Ds is at the level of a 6-8 month old with speech, no words, limited babble (no bababa, dadada) his main noise is - 'uh', and he is often silent. Sometimes he points to his mouth and moves it as if to talk, but he doesn't seem to be able to control the way his tongue moves very well, and so even if his verbalisation improves, I think it would be very difficult to understand what he says. However, he has fairly good understanding, and communicates a lot through his eyes and his body language, and to me it seems the most important thing is not to teach him to speak, but to communicate, and makaton signing is a very good way of doing that, obviously the more people around him that can understand the signs, the less frustrating the world will be for ds.
I think the thing about Makaton that makes it such a perfect thing to introduce into the early years curriculum, is that it is so simple for children to learn, it is whole word signs, that are not complex, and are universal. It is useful for all children with a speech delay or social communication problem, and is something that can be taught, simply through use - so songs being sung in assembly, with the signs included, simple signs being stuck up around the classroom.
i think it is wonderful that a programme like Something Special, has become so mainstream and loved by all children, because it helps children to realise that children with disabilities and additional needs are just like them, and with children with sn being part of mainstream education, I think it is really important that we include the language that is so helpful for communication in the curriculum.
