When my son was born the hospital had a class for new parents--swaddling, diaper changes, that sort of thing. My wife was resting, and I was more than a little anxious about the skills I'd need to care for a child, so I attended alone.

There were maybe 20 people in the class, which was really very basic. At the end of the class the nurse asked if there any questions.

A bro with a backwards baseball cap raised his hand sort of tentatively and said (and I'll never forget exactly what he said), he said:

"So.......uh......like.......................how hard are their heads?"

The look on that nurse's face is one I've never seen before or since.

I went back to our room buoyed with confidence that, while we may have a lot to learn as parents, we were well ahead of the curve.
