Perfect for you if...

You're pregnant and tired of being told what you can't do without anyone explaining why.
You make decisions based on evidence, not fear, and want the actual data behind those rules.
You're suspicious of blanket recommendations and want to know what risks are real versus invented.

Maybe not for you if...

You prefer straightforward medical guidance without questioning authority or diving into statistical nuance.
You're looking for a warm, reassuring pregnancy companion rather than a data-driven interrogation.
You want meal plans, exercise routines, or week-by-week development guides. This is purely about decision-making.

About this book

An economist examines the scientific evidence behind standard pregnancy recommendations and finds that many are misguided or incorrect. Pregnant women often receive rules about foods to avoid—cold cuts, sushi, alcohol, coffee—and prenatal testing guidelines without clear explanations for why these restrictions exist. This book evaluates the data behind accepted pregnancy practices, covering topics from the effects of caffeine to risks associated with gardening. It aims to help pregnant women understand the reasoning behind recommendations so they can make informed decisions about their own pregnancies. The author, an award-winning economist, wrote this book after conducting her own research while pregnant.
