One father recently spoke with me about the trouble he was having putting his son to sleep at night*—a ritual that typically involved about three-quarters of an hour of fighting. We did the arithmetic. Forty-five minutes a day, seven days a week—that’s three hundred minutes, or five hours, a week. Five hours for each of the four weeks of a month—that’s twenty hours per month. Twenty hours a month for twelve months is two hundred and forty hours a year. That’s a month and a half of standard forty-hour work weeks.
