Women are given messages all through their lives that they shouldn’t lead.

Study after study suggests that the pressure society places on women to stay home and do “what’s best for the child” is based on emotion, not evidence. In 1991, the Early Child Care Research Network, under the auspices of the National Institute of Child Health and Human Development, initiated the most ambitious and comprehensive study to date on the relationship between child care and child development, and in particular on the effect of exclusive maternal care versus child care. The Research Network, which comprised more than thirty child development experts from leading universities across the country, spent eighteen months designing the study. They tracked more than one thousand children over the course of fifteen years, repeatedly assessing the children’s cognitive skills, language abilities, and social behaviors. Dozens of papers have been published about what they found.23 In 2006, the researchers released a report summarizing their findings, which concluded that “children who were cared for exclusively by their mothers did not develop differently than those who were also cared for by others.”24 They found no gap in cognitive skills, language competence, social competence, ability to build and maintain relationships, or in the quality of the mother-child bond.25 Parental behavioral factors — including fathers who are responsive and positive, mothers who favor “self-directed child behavior,” and parents with emotional intimacy in their marriages — influence a child’s development two to three times more than any form of child care.26 One of the findings is worth reading slowly, maybe even twice: “Exclusive maternal care was not related to better or worse outcomes for children. There is, thus, no reason for mothers to feel as though they are harming their children if they decide to work.

Imagine that a career is like a marathon — a long, grueling, and ultimately rewarding endeavor. Now imagine a marathon where both men and women arrive at the starting line equally fit and trained. The gun goes off. The men and women run side by side. The male marathoners are routinely cheered on: “Lookin’ strong! On your way!” But the female runners hear a different message. “You know you don’t have to do this!” the crowd shouts. Or “Good start — but you probably won’t want to finish.” The farther the marathoners run, the louder the cries grow for the men: “Keep going! You’ve got this!” But the women hear more and more doubts about their efforts. External voices, and often their own internal voice, repeatedly question their decision to keep running. The voices can even grow hostile. As the women struggle to endure the rigors of the race, spectators shout, “Why are you running when your children need you at home?” Back in 1997, Debi Hemmeter was a rising
