As a professor of infant and child development, Vanessa LoBue had certain expectations about how pregnancy and motherhood would go. Experiencing it was a different story. As she learned, the first few months of parenthood are much harder than anyone tells you. Written in real time as LoBue proceeded through pregnancy and first-time parenthood, 9 Months In, 9 Months Out explores the science of infant development alongside an honest account of how that science translates to a mother's experience.
