What to Expect When You're Expecting

Announcing a brand new, cover-to-cover revision of America's pregnancy bible. What to Expect When You're Expecting is a perennial New York Times bestseller and one of USA Today's 25 most influential books of the past 25 years. It's read by more than 90% of pregnant women who read a pregnancy book—the most iconic, must-have book for parents-to-be, with over 14.5 million copies in print.

Now comes the Fourth Edition, a new book for a new generation of expectant moms—featuring a new look, a fresh perspective, and a friendlier-than-ever voice. It's filled with the most up-to-date information reflecting not only what's new in pregnancy, but what's relevant to pregnant women. Heidi Murkoff has rewritten every section of the book, answering dozens of new questions and including loads of new asked-for material, such as a detailed week-by-week fetal development section in each of the monthly chapters, an expanded chapter on pre-conception, and a brand new one on carrying multiples. More comprehensive, reassuring, and empathetic than ever, the Fourth Edition incorporates the most recent developments in obstetrics and addresses the most current lifestyle trends (from tattooing and belly piercing to Botox and aromatherapy). There's more than ever on pregnancy matters practical (including an expanded section on workplace concerns), physical (with more symptoms, more solutions), emotional (more advice on riding the mood roller coaster), nutritional (from low-carb to vegan, from junk food–dependent to caffeine-addicted), and sexual (what's hot and what's not in pregnant lovemaking), as well as much more support for that very important partner in parenting, the dad-to-be.

Overflowing with tips, helpful hints, and humor (a pregnant woman's best friend), this new edition is more accessible and easier to use than ever before. It's everything parents-to-be have come to expect from What to Expect...only better?.

It all started with a baby…and a book. Heidi Murkoff conceived the idea for What to Expect When You're Expecting during her first pregnancy, when she couldn’t find answers to her questions or reassurance for her worries in the books she’d turned to for much-needed advice. Determined to write a guide that would help other expectant parents sleep better at night, Heidi delivered the proposal for What to Expect When You’re Expecting just hours before delivering her daughter, Emma.

Dubbed the “pregnancy bible”, the iconic New York Times bestseller is now in its all-new fourth edition, with over 17 million copies in print, and according to USA Today, is read by 93 percent of women who read a pregnancy book. Other titles in the series include Eating Well When You’re Expecting, What to Expect the First Year, What to Expect Before You’re Expecting (a complete preconception plan), and the newest member of the What to Expect family: What to Expect the Second Year, the must-have guide for parents of toddlers. The What to Expect books have sold more than 34 million copies in the US alone, and are published in over 30 languages.

In 2005, Heidi expanded the What to Expect (WTE) brand online with WhatToExpect.com – the interactive, state-of-the-internet companion to the WTE books, and home to a vibrant, vast, yet close-knit community of 3 million parents. In 2009, WTE went mobile with the WTE Pregnancy Tracker (the most popular pregnancy app in the world), the WTE Fertility Tracker, the WTE Baby Name Finder, and the WTE First Year Tracker.
Heidi’s passionate commitment to moms and babies led to the creation of the What to Expect Foundation, a nonprofit organization dedicated to helping underserved families expect healthy pregnancies, safe deliveries, and healthy, happy babies. With a beautiful, culturally appropriate low-literac
