Only on the "CBS This Morning" podcast, reproductive psychiatrist Dr. Alexandra Sacks joins CBS News medical contributor Dr. Tara Narula to define "matrescence," the period when women transition to motherhood. Sacks explains how the medical community doesn't adequately prepare women for portion of their lives, which includes physical and emotional changes reminiscent of adolescence. She shares why her "Motherhood Sessions" podcast from Gimlet Media is a valuable public health tool that gives women the opportunity to have candid conversations on the complex emotions and guilt they don't always want to discuss with their friends and family. "Motherhood Sessions" is available on Spotify or wherever you get your podcasts.
