"For a man, the nine months of pregnancy pass pretty much like any other nine months of an adult's life; Tom can refer to 'when the baby arrives' as if it's not already here in the room with us, aiming lusty kicks into the depths of my stomach."

[By the way, an excellent work of fiction I got from the library a few days ago. A really quick read, and engrossing even if you've never been and never plan to become pregnant.]
