I only have a very small sample to draw on, but out of the children in Ds2's SN class, he is the only one who jabbers and babbles continually. He does use words to ask for the things he wants but the rest of the time he is making a huge variety of noises, nonsense (to us) syllable strings and repetitive sounds/words. We are so used to it that it barely registers as being unusual any more, but found myself wondering today how many other children do it. I'd also like to know if he will always do it or whether its something that some children grow out of. Out of everything he does, it's probably the one that draws attention to him most as being different - although professionals have commented that its positive because an awful lot of it is made up of speech sounds.
