My DS2 had speech delay discovered at nursery, and later was diagnosed with a speech and language disorder - he had difficulty processing language, no automatic filing system for new words. It was a problem with his receptive and expressive language. It was really noticeable when he was little when you asked him a question and he could tell it was a question from the way you spoke but didn't know which question, so would answer randomly. EG 'what's your favourite colour?' 'teddy bear'.
He got through primary school ok, we paid through the nose for private weekly speech therapy which really helped and taught him strategies to get round his problems, which were not severe, but had started to have a big effect on his self esteem and behaviour.
In year 4 a friend of a friend suggested The Listening Centre in Lewes. I looked into it and although I was skeptical - it looked strange quite frankly, and it cost quite a bit of money - I gave it a go as I was really worried about him at the time. Anyway, it was the best thing I could have done, and I really recommend it to anyone concerned on this thread. It may not be for everyone, but it is definitely worth looking into.
My DS2 is now a happy, confident 15 yr old, who is in GCSE year and doing pretty well, he is not exceptionally academic, but is doing well at the top of the middle sets for most things. I would never have thought this possible in primary school and am so happy to have an average child!
I just think people should know about this as an option, there are more places that do this therapy now and it's becoming better known. It was definitely the thing that changed my DS2s life, and helped with confidence, behaviour, ability to learn and coordination to name a few. Take a look at the website and decide for yourself. www.listeningcentre.co.uk. and don't be put off by the weird photo on the front page (if its still there)! Or just google listening therapy.
I just wanted to share. Good luck.
