Cribsheet: A Data-Driven Guide to Better, More Relaxed Parenting, from Birth to Preschool

A professor of Economics at Brown University, Oster specializes in health economics and statistical methods. Her research primarily focuses on understanding why individuals often deviate from making “rational” health choices. Transitioning from the academic sphere to parenting literature, Oster’s expertise in Cribsheet is underscored by her commitment to applying rigorous analytical methods to the often overwhelming and contradictory advice surrounding pregnancy and parenting.

Oster gained widespread recognition with the 2013 publication of her book Expecting Better: Why the Conventional Pregnancy Wisdom Is Wrong—and What You Really Need to Know. In this book, she critically examines common pregnancy advice, scrutinizing the scientific evidence behind recommendations concerning alcohol consumption, caffeine intake, and other aspects of prenatal care. Oster’s approach is grounded in her training as an economist, and she advocates for a more evidence-based decision-making process during pregnancy.

Building on the foundation laid by Expecting Better, Oster extends this approach to “Cribsheet,” a book specifically written for new parents struggling with crucial decisions related to early childhood. Through the lens of statistical analysis, Oster tackles critical decisions faced by parents, ranging from breastfeeding practices to co-sleeping and potty training. Her commitment to evidence-based decision-making becomes evident as she provides clarity and rationality to choices often clouded by myths and conflicting advice.
