I don't know how to say this and not sound silly...but Autism Spectrum Disorders (ASD) isn't as bad as you think. My son was dxd. first (WHEN he finally got dxd...with Pervasive Developmental Disorder (PDD)-not otherwise specified). The more interventions you can get, the better. Also, believe it or not, as Autism Spectrum Disorders (ASD) kids age, they do not tend to have severe behavioral issues and they do tend to improve. Many Autism Spectrum Disorders (ASD) kids NEVER have behavioral issues. They are wired differently and, yes, concrete thinkers who dislike change and usually have incredibly hard times understanding people, but I've seen huge improvements in my son on all fronts. And I've seen improvements in many Autism Spectrum Disorders (ASD) kids. They are all different too. Like V, Sonic can recognize facial expressions, and that alone is a good strength. People communicate with those expressions.
Sonic had a genetics test to rule out any reason for his Autism Spectrum Disorders (ASD). The tests all came back negative, but we were still glad that we did the test. It's just a blood test. A few things they looked for are Prader-Wille Syndrome and Fragile X Syndrome.
