I worked with three animators, Tim Divall, Daniela Sherer and Amanda Bonaiuto, to create and write a series of three videos for The Atlantic on the history of our understanding of how children develop. From shifts in the 1960s around our understanding of children's environment and its effects on their behavior, to an increased focus on the environment's effect on children's brains, to a greater understanding of trauma, these three videos trace a burgeoning understanding of the complexity of children's growth.
