Neuroscience shows us 85 percent of human brain development occurs in the first five years of life. And our next guest Dr. Dana Suskind says we must make healthy brain development our North Star—the organizing principle around which our entire society is oriented. And we must do so by elevating our expectations for how society supports parents—the first and most important architects of children’s brains. Dr. Suskind’s new book is PARENT NATION: Unlocking Every Child’s Potential, Fulfilling Society’s Promise.
