Autistic 3 Year Old Sings Justin Bieber’s Song “Baby” [VIDEO]

My son has autism. he has about 4 words in his vocabulary but can mimic just about any word. He has also had a pretty good knack to pitch-match if someone was singing an elongated note.
The other day we were both waiting in the car when Justin Bieber's "Baby" came on local radio station 107.3 KFFM in Yakima, WA.

We were just waiting patiently in the car (as patient as any 3 year old with autism can be) when after the song my son starting singing the "Baby, Baby, Baby, OHHHH" part over and over for about 3 minutes straight. It put a smile on my face as he usually don't do things like this. I was able to get my phone out in time to get only about 10 seconds of this until he saw the camera, then he stopped. Here's the 10 seconds of footage I did catch.
