Hi my DS was 5 in September. He was starting to say little things at 8/10 months - trying to say all gone, quack, woof - I thought, wow brilliant, he'll be chatting away in no time! By 2 he couldn't say anything at all - at all! he made a funny nasal sound from the back of the throat, but spoke in full sentences with proper intonation - I have some videos of him if anyone would like to see.
He's had every test going, been under SALT for 3 years. Had absolutely no issues at all with understanding. He had some group sessons which were uselss for himnd many days I felt like crying - fed up of people talking to him and having to keep explaining that he can't speak - they all thought he just won't speak etc, it was really awful and you have my sympathy. He couldn't say Mummy or dadday - in fact no names at all. He had examinations from dentists, cleft lip specialists to check his mouth, even a special test for a certain type of epilepsy. He had loads part sts done for his understanding and we took part in a trial to do with speech and personalities - when she last assessed him at about 3 years 8 months, his expressive speech was just about at 12 months and his understanding at about age 6, so the gap between the 2 was huge.
After being really unhappy with the group sessions, he got a one to one SALT for one day a week, she has been brilliant - so so nice and he started to be able to to s - she had to teach him how to form his mouth to say the words.
Fast forward to now, he is in mainstream and his peech is so amazing there is no way you would know - I still know that he has way more in his head than he can get out in the time he has to say things and he has a en stresin that he prolongs words sometimes and when stressed/upset/tired he has to take quick short breaths before speaking - I notice he is nowhere near as fluent as bright children in his class though - although his vocabulary of words is way way above theirs, always used in the correct context too. He is always asking the meaning of words.
He is under a paed who isn't always very helpful
and we have no diagnosis as yet, but he is most probably Aspergers - though I know the paed wants to say not becuase of the no speech thing - though his vocab is such now, that it fits (obv we now have other issues with him socially, that is very hard) He has some oddities, and he still gets frustrated with words but his word bank in his head is amazing - also look up cued it wiulation, this can be very useful and we used it with DS sometimes.
There are loads of instances where I still see his speech problems, where I know he can't get things out quick enough, where he just doesn't bother saying what he was going to say sometimes, or starts then says "oh it doesn't matter" so still times when I am sad for him.
I can look back at videos of him and cry - but like I said, happy for anyone to see some vids of him if I can sort it as I know these things often helped me - or if anyone has any questions
I know that if you just heard him now there is no way you would believe what things were like for us
