Cribsheet by Emily Oster

Cribsheet, Emily Oster's follow-up, applies rigorous data analysis to the first years of parenting, cutting through guilt-inducing myths. She examines what research actually says about breastfeeding versus formula, sleep training, and screen time, concluding that differences are smaller than most believe—for instance, formula-fed babies show only a 2% lower immunity rate at age 1. This book is faster than the typical parenting guide in delivering clear verdicts, offering evidence that reduces pressure and empowers logical choices.
