As a toddler, Marlo Mack’s child voiced that her gender didn’t match the one assigned to her at birth. The writer and producer of the “How to Be a Girl” podcast joins host Krys Boyd to discuss the challenges and triumphs of raising a transgender child, and how she’s grown in her approaches to gender and sexuality. Her book is called “How to Be a Girl: A Mother’s Memoir of Raising Her Transgender Daughter.”
