After the third consecutive night of no sleep, I was starting to lose it. Our newborn daughter, who had looked so sweet and angelic in the moments right after her birth (9 on the APGAR - you go, girl!) had morphed into a demonic nighttime presence. She needed less sleep than any human I had ever encountered. And when she did snooze, she did so with hair-trigger sensitivity to the environmental cues to full alertness: an adult cranium touching a pillow, an eyelid closing and not reopening within a tenth of a second.
