We should compare notes about are sons! Kids with autism are all so different and each one is affected differently. My son has a hard time with reading and comprehension, and orginization to, where as he is a wiz at math and science. I swear he has a calculator in his brain. And he loves his car and is putzing with it all the time!
He LOVES music his Ipod is his favorite thing, what is nice with the high school he attends they allow the kids to have MP3 players. He uses his everday it blocks out all the other noise around him. For some reason it helps him consentrate better??

Thats funny you should mention that your son loved commercials at that age mine love music! Especially music from Barney! We sang those songs all the time, and songs from the Lion King!
