Heidi Murkoff’s What to Expect is the world’s most popular pregnancy and parenting brand. Her bestselling What to Expect® series includes What to Expect When You're Expecting, the pregnancy “bible” now in its fourth edition; Eating Well When You're Expecting, What to Expect the First Year; and What to Expect the Toddler Years. The latest addition to the What to Expect family, What to Expect Before You're Expecting, a complete step-by-step guide to conception, was published in Spring 2009. The series has more than 32 million copies in print in the U.S. alone, and is published in over 30 languages.

Heidi’s passionate commitment to helping parents led her to cofound the What to Expect Foundation, a thriving nonprofit organization dedicated to providing information, support, and literacy skills to low-income families– so that every family can expect a healthier pregnancy, a safer delivery, and a healthier, happier baby. So far, the Foundation’s groundbreaking Baby Basics prenatal health literacy program has helped more than 500,000 underserved families nationwide.

WhatToExpect.com, the online companion to the What to Expect book series, is a vibrant, fast-growing community of moms-to-be and new moms (and dads), and is home to over a million members.

Heidi has two children, Emma and Wyatt, and lives in Los Angeles with her husband, Erik.
