Expecting Better: Why the Conventional Pregnancy Wisdom Is Wrong--and What You Really Need to Know (The ParentData Series)

Fully revised and updated for 2025, from the bestselling author of Cribsheet, The Family Firm, and The Unexpected — Emily Oster brings data-driven clarity to pregnancy decisions many doctors skip.

“A revelation for curious mothers-to-be whose doctors fail to lay out the pros and cons of that morning latte, let alone discuss real science.” — The New York Times • “Emily Oster is the non-judgmental girlfriend holding our hand and guiding us through pregnancy and motherhood.” — Amy Schumer

Pregnancy can overwhelm even the most prepared women with rules—avoid sushi, coffee, wine—often without clear evidence. Award-winning economist Emily Oster examines the data behind common pregnancy advice and finds many recommendations are misguided or flat-out wrong. Expecting Better empowers parents-to-be to make informed choices by explaining the evidence on topics like caffeine, prenatal testing, alcohol, food safety, and everyday risks.

Whether you want a calm, evidence-based pregnancy or clarity on specific decisions, Expecting Better gives you the tools to weigh risks and benefits and enjoy a healthier, more relaxed pregnancy—sometimes with the occasional glass of wine.
