DS 5 has recently been diagnosed as suffering from selective mutism and SID. Both my husband and myself work in the mental health field and neither of us had heard of it before. We thought DS may be dx as having Aspergers, but after thinking about it and taking him to several evaluations, we determined that he did have social skills, but was "choosing" (not really, but the best word I could think of) not to use them, which would rule it out. So, at our last evaul the psychologist dx as having selective mutism. I was wondering if anyone has had any experience with it or knows any good resources. I did find some sites on the web, but they were fairly unorganized. Thanks.
