My son is 18 and had a late diagnosis of autism at 16. He was later diagnosed as having selective mutism by an educational psychologist. I really want to help him as this is the main thing that is affecting his life as he cannot make friends and could not go to a recent job interview due to nerves of talking. Has anyone had experience of speech and Language therapist as i was told by CAMHS that speech therapy would not be beneficial to him, but I just dont know what to do next.
