The United States is an outlier when it comes to parents. Compared to similar countries, the U.S. has the largest happiness gap between the 63 million parents and the child-free. This statistic is not shocking when you consider how other societies support parents with things like paid parental leave and high-quality child care.

In her new book, Parent Nation: Unlocking Every Child's Potential, Fulfilling Society's Promise, Prof. Dana Suskind of the University of Chicago makes the case for how America can—and should—improve societal support for parents during the early childhood period.

Through her work as director of the Pediatric Cochlear Implant Program and co-director of the Thirty Million Words Initiative, Suskind has observed why the first three years of a child's life are the most crucial for their brain development. She argues that investing in early childhood by supporting parents—notably, paid parental and family leave—is not only beneficial for them, but it's also beneficial for our economy and society.
