He has real trouble with any words being with a vowel. He can't get the initial sound out - I want the a,a,a,a,a,a,a,a,a,a (for up to a minute) ambulance. I am really worried that I have caused it as a few weeks ago, I tried to teach hime to say 'I' instead of 'me'. Since then, he has developed this stutter that is really quite bad in his every day language. Before this, he did not stutter like this. He has become upset and says 'mummy I can't speak any more'. Unfortunately, when he first started the stutter, I responded in the wrong way and told him he neede to speak properly if people were to understand him (I KNOW this is the worst thing I could have done now). Now I am ignoring the stutter totally but it still persists. I am really worried and very guilty.
