When I had finished singing. Tessa wasn't quite asleep, but she looked drowsy. I rose and headed toward the crib to lay her down, but she immediately sat up and started to fuss. Okay, I thought, she needs a little more time, So I sat back down and sang the lullabies again, waiting for her eyes to close. They didn't. I sang my songs one more time, throwing in“The Alphabet Song”for good measure, until finally she seemed to be asleep. I laid her in the crib and turned to leave. Then I hit a squeaky floorboard. Tessa's little head popped up, and she began to wail.
