One evening, while his three-month-old son Charlie briefly slept, Matt Coyne staggered to his desk, opened his laptop, and wrote a side-splittingly funny Facebook post about early fatherhood: Comparing his diaper-changing skills to that of a Formula One pit crew, birth to a Saw movie, and the sound of a baby crying at 3am to “having the inside of your skill sandpapered by an angry Viking,” he shared his observations with friends and family—and soon, to his surprise, the world. In the spirit of that post, which became an instant sensation, Man vs. Baby is the tale of one man’s journey through the first year of parenthood, told with wit, humor, and heart.
