My son is very exceptional. He was tested by a neurologist at Texas Children's Hospital and his IQ is extremely high. He also has Sensory Processing Disorder and is possibly on the spectrum. He will be 5 this summer.

In the past week, he began speaking a new language. At first, I wasn't sure what language he was speaking because he has made up his own languages in the past. But, now that I've done some research, it is clearly Russian. He seems to speak it fluently.

I don't know anyone who speaks Russian and since he only has access to DVDs, I know he didn't learn it from TV.

Has anyone ever heard of this before?
