The ParentData Series – serie

Fully revised and updated for 2025, from the bestselling author of Cribsheet, The Family Firm, and The Unexpected“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. She has done the work to get us the hard facts in a soft, understandable way.” —Amy SchumerThe award-winning economist named one of TIME Magazine’s 100 most influential people disproves standard recommendations about pregnancy to empower women while they're expecting. Pregnancy—unquestionably one of the most pro­found, meaningful experiences of adulthood—can reduce otherwise intelligent women to, well, babies. Pregnant women are told to avoid cold cuts, sushi, alcohol, and coffee without ever being told why these are forbidden. Rules for prenatal testing are similarly unexplained. Parents-to-be desperately want a resource that empowers them to make their own right choices.When award-winning economist Emily Oster was a mom-to-be herself, she evaluated the data behind the accepted rules of pregnancy, and discovered that most are often misguided and some are just flat-out wrong. Debunking myths and explaining everything from the real effects of caffeine to the surprising dangers of gardening, Expecting Better is the book for every pregnant woman who wants to enjoy a healthy and relaxed pregnancy—and the occasional glass of wine.

From the author of Expecting Better, The Family Firm, and The Unexpected an economist's guide to the early years of parenting.“Both refreshing and useful. With so many parenting theories driving us all a bit batty, this is the type of book that we need to help calm things down.” —LA Times“The book is jampacked with information, but it’s also a delightful read because Oster is such a good writer.” —NPR With Expecting Better, award-winning economist Emily Oster spotted a need in the pregnancy market for advice that gave women the information they needed to make the best decision for their own pregnancies. By digging into the data, Oster found that much of the conventional pregnancy wisdom was wrong. In Cribsheet, she now tackles an even greater challenge: decision-making in the early years of parenting.  As any new parent knows, there is an abundance of often-conflicting advice hurled at you from doctors, family, friends, and strangers on the internet. From the earliest days, parents get the message that they must make certain choices around feeding, sleep, and schedule or all will be lost. There's a rule—or three—for everything. But the benefits of these choices can be overstated, and the trade-offs can be profound. How do you make your own best decision?  Armed with the data, Oster finds that the conventional wisdom doesn't always hold up. She debunks myths around breastfeeding (not a panacea), sleep training (not so bad!), potty training (wait until they're ready or possibly bribe with M&Ms), language acquisition (early talkers aren't necessarily geniuses), and many other topics. She also shows parents how to think through freighted questions like if and how to go back to work, how to think about toddler discipline, and how to have a relationship and parent at the same time.  Economics is the science of decision-making, and Cribsheet is a thinking parent's guide to the chaos and frequent misinformation of the early years. Emily Oster is a trained expert—and mom of two—who can empower us to make better, less fraught decisions—and stay sane in the years before preschool.
