When i started seeing my speech pathologist, She did some research about what would be best for us to do and she came back with the camper down program, I was 31 at the time. If you can afford it, or have access to a speech pathologist who is good and willing to do it with you, Well worth it. It is one of the programs which has proven results. The public speech pathologist I saw, Was getting a lot help from Sydney university when she was seeing me, But she always said, If i could afford It to do it with them.
