Is this really the same baby?

Did you ever get scared that your baby was going to be switched around with someone else's baby in the hospital? Well, I know that didn't happen to me, cuz I had the cutest baby ever in the hospital, and I came home with the cutest baby ever. But, I was just comparing these two pictures. One I took when Michael was maybe 3 or 4 months old. And then the other two, I took last week. Although he is still the cutest boy ever to hit the face of this planet, he has just changed soooo much. (No really?) I know that's what you're thinking. But I'm being a reminiscent mother.
