In a world where zygotes need preschool applications and the wrong stroller can label you an unfit mother, pregnant professionals turn to Katie Johnson, San Francisco's most prestigious baby planner, long before their baby bumps become obvious under their Armani suits. But setting up her clients with the latest must-have baby gadgets, top-notch doulas, and most desirable playgroups is just the start. For the anxious mommies who have her on speed dial, Katie is also therapist, referee, and best friend all in one. Secretly, however, Katie longs for a baby of her own. Her husband, Alex, refuses to do more than what he calls keeping an open mind, but when he gives her reason to doubt he means even that, Katie throws herself into helping her most clueless client of all. Seth Harris is raising his newborn daughter solo. While Katie helps him navigate this difficult journey, she learns ones very important lesson about family: How we nurture is the true nature of love.
