When I was expecting my first baby, a six-year-old neighborhood girl was particularly curious. She wanted to see the baby furniture and hear our list of possible names.

When she asked where the baby was, I was a walking show-and-tell even at four months. But then she asked the question that probably had been foremost in her mind: "How did the baby get in there?"

"I think you'd better ask your mother about that," I said.

"Oh, I tried that," she confessed. "Nobody in my family knows!"
