What to Expect series 
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 advice. Determined to write a guide that would help other expectant parents sleep better at night, Murkoff delivered the proposal for What to Expect When You're Expecting hours before delivering her daughter.
The The New York Times bestseller is now in its fourth edition, with more than 17 million copies in print. According to USA Today, What to Expect When You're Expecting is read by 93 percent of women who read a pregnancy book. USA Today also named What to Expect When You're Expecting one of the most influential books of the last 25 years.
The sequel, What to Expect: The First Year, has sold over 10 million copies and is in its 2nd edition. Other titles in the series include What to Eat When You're Expecting, What to Expect Before You're Expecting (a complete preconception plan), and the newest member of the What to Expect series: 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 U.S. alone and are published in more than 30 languages.
Murkoff's What to Expect Kids picture book series for preschoolers include What to Expect When Mommy's Having a Baby, What to Expect When the New Baby Comes Home, What to Expect When You Use the Potty, and What to Expect at Preschool.
In 2005, Murkoff expanded the What to Expect (WTE) brand online with www.whattoexpect.com as a companion to the books. In 2009, WTE went mobile with the WTE Pregnancy Tracker (a popular pregnancy app), the WTE Fertility Tracker, the WTE Baby Name Finder, and the WTE First Year Tracker.
What to Expect Foundation 
Murkoff created the What to Expect Foundation (whattoexpect.org) as a nonprofit organization dedicated to helping underserved families have healthy pregnancies, safe deliveries, and healthy, happy babies. The WTE Foundation's Baby Basics program has helped over 500,000 expectant moms-to-be in need and their babies and is currently preparing a global initiative in an effort to help moms in need around the world.
