Hi Bubblagirl - just want to add my own story re my DS delayed speech. He has just turned 4.
DS was always a quiet baby, he never did the whole baby talk thing, he never made noises really at all - he only cried. I mentioned it to my HV when he was 2 and said that she could refer me to the ST if I really wanted. I don't think she thought it necessary at the time, but I knew that the couple of words he could say were badly prounounced and he made no effort (despite us trying) to talk at all. He had his own sign language which worked well and a couple of made up words for the important stuff.
We were reffered quite quickly and following an assessment from the ST, they agreed to a course of Therapy.
At first there wasn't much change, but he was still young. It was suggested that I put him into our school nursery early so he had to interact with other children (DS is only child).
His speech improved, but he couldn't pronounce constinants and didn't put endings / beginnings on words - nobody really understood him. But, once he started nursery (3.5)he really started improving.
We still go to the ST and he isn't anywhere near 'normal' - when he concentrates and we remind him he is quite good, but his spontaneous speech is stil a bit iffy !
The teachers at school have been great and now he has to make himself understood to his piers, he is coming along leaps and bounds.
All you can do is encourage him, he still sometimes gets fustrated - but the ST gave us some great games and photocopied loads of excerices for us to do at home.
It really does get better....I'm pleased that I pushed it from such a young age as otherwise he wouldn't have got referred until school.
Sorry, for such a long and rambling post.
