In this episode of the Motherly Podcast, Liz speaks with Abigail Tucker about her book, Mom Genes: Inside the New Science of Our Ancient Maternal Instinct. In their conversation, they explore the biology and science of motherhood -- the second adolescence we go through after giving birth, the science behind our maternal impulses, our so-called “mommy brain,” and some of the superpowers of resilience, adaptability, and heightened perception that we acquire after becoming a mother.
