History 
Author Heidi Murkoff cites her own quest for reassuring information during her first pregnancy as being the motivation for developing What to Expect When You're Expecting. Murkoff collaborated with her mother Arlene Eisenberg, a freelance journalist, and her sister Sandee Hathway, a nurse, when writing the first three editions of the pregnancy guide.

Its iconic title emerged when an employee of the publisher suggested it as a subtitle for the temporarily titled manuscript, "Pregnancy:" By publication, the subtitle had claimed the top spot.

Although the book's initial print run was small, word of mouth and innovative promotion led to sales that increased in every subsequent year.

What to Expect books

What to Expect When You’re Expecting 
The book presents advice in a question-and-answer format. It proceeds chronologically from the time a woman first begins to suspect pregnancy, through each of the nine months (with one chapter devoted to each), and into the postpartum period. The beginning of each chapter includes a section called “Your Body This Month,” which succinctly lists common physical and emotional changes and symptoms a woman may be experiencing, and gives information on what a woman can expect when visiting her doctor or nurse midwife during checkups. Also included early in each chapter is a section entitled "Your Baby This Month" which displays pictures of  the growing embryo then fetus. An additional section titled "What You May Be Concerned About" is designed to address a wide range of concerns, problems and life trends. There are also “For Dads” boxes integrated throughout the book that speak to fathers’ unique concerns as partners in pregnancy, childbirth, and parenting.

The book's appendix lists additional sources of information and resources including government organizations, associations and foundations.

Controversy
What to Expect When You're Expecting has been criticized for promoting paranoia and fear among pregnant women for focusing on complications and for its extremely strict dietary guidelines. Murkoff also has no medical training and has been further criticized for stating she asks obstetricians to comment on manuscripts only late in the writing and editing processes. With the first publishing of the book being in 1984, one reason it is considered problematic is due to the many old and unrevised printings in public circulation. Although wording is revised with every single printing of the book with major rewrites indicated by new editions to respond to critiques, older copies are passed down by women to their pregnant peers.

The Science Based Medicine blog criticized the book for its recommendations of Complementary and Alternative Medicines (CAM), such as Acupuncture, Reflexology, Aromatherapy and Homeopathy. The blog post concludes: There is no credible scientific evidence to support any of these recommendations. It could be argued that this is all feel-good, “keep-the-patient entertained” advice with little chance of direct harm. But it is deceptive and dishonest to represent these modalities as effective treatments based on science, especially in a book that is otherwise scientifically reliable.
