Does anyone else's baby do this?

Yes, for about 6 months of my sons life I could never watch "a baby story" or any show with any baby for that matter... it didn't matter if my son was sleeping or laughing he would suddenly burst into tears every time he heard a baby cry. I always thought it was funny, and as soon as I turned the TV off he was fine. He also cried every time a baby cried in a restaurant or whenever we were out.
