One of my friends described DS2 as 'non-verbal' today in casual conversation. It didn't really upset me - but it did bring me up with a bit of a jolt. I wondered if that's how others see him and if I'm being a bit optimistic in descrbing him as 'verbal.
He uses single words and a very few learned phrases. He'll say 'I want X please' but you have to prompt it. He only uses words to request - very very rarely to comment. We can understand his speech but it's obvious to me that others often can't - even words I think he says quite clearly. He babbles a lot and mixed in with this are real words and phrases, usually echolaic, which are not in context (to me anyway - they may be to him!).
I guess to describe him as 'verbal' suggests an ease with words which he most definitely doesn't have. But I wouldn't describes him as non-verbal - unless to other people that means unable to communicate clearly in words outside his immediate family (and 1:1s at school). I sometimes describe him as 'minimally verbal' but don't like doing so - seems very negative when he works so hard to communicate!
