Parenting questions, answered with research rather than fear.
Tracy Cassels, PhD, puts common Western parenting advice, from warnings against bedsharing to crying it out, to researchers and authors and asks what the evidence actually supports. The conversations take care to separate what studies contradict from what nobody has studied yet, and they stay warm toward parents.

The Evolutionary Parenting Podcast is hosted by Tracy Cassels, PhD, and it keeps asking one thing of the advice parents are given: what does the evidence actually say? The recent episode titles are all phrased as questions. Most episodes pair the host with a researcher or author, and the talk stays close to studies, definitions and the places where data is missing. Sleep is a subject she openly admits to favouring. 'Ep. 66: Safe Sleep Education: Is Abstinence Only the Only Way?' starts from the warning new parents in Western, educated, industrialized, rich and democratic countries tend to hear: do not sleep with your baby. The host calls that fear-based messaging. The conversation moves toward reducing the risks parents can control, like keeping heavy bedding and pillows away from a baby, and it notes that no sleep setup, shared or separate, is entirely risk-free. 'Ep. 62: What do we really know about Crying It Out?' covers crying it out and its modified form, controlled comforting, and how the age at which it gets recommended has crept younger. One sharp exchange criticises research that counts a sleep problem as whatever a parent perceives, even though society has already told parents to expect one. The closing advice is plain: other methods exist that do not require leaving a baby to cry, and underlying issues deserve a look first. The range goes well past bedtime. Dr. Greer Kirschenbaum, a neuroscientist, doula and educator, returns to talk about The Nurture Revolution and the years from zero to three. That conversation stays on why nurture is hard to learn for adults who never received much of it. It also separates research that contradicts an idea from research that simply has not been done. Dr. B.J. Woodstein, author of The Portrayal of Breastfeeding in Literature, brings a Swedish comparison to the question of how breastfeeding is represented in Western cultures. With Dr. Lauren Franz of Duke University's Center for Autism and Brain Development, the show takes on the apparent tension between neurodiversity and early intervention for autism, and the host suggests that support should not depend on a diagnostic label. In 'Ep. 37: Can Babywearing Help with Mother-Infant Relationships?', the guest is Dr. Leila Rankin-Williams, a certified babywearing educator whose randomized studies involved teenage mothers. The host points out that nobody had strollers in the Stone Age. That aside sums up the show's approach: modern habits are measured against how babies have been kept close for most of human history. The delivery is conversational and fluent in research, warm toward parents and pointed about vague definitions and blanket warnings. Closings point to concrete help, from a local IBCLC for breastfeeding struggles to the Beyond Sleep Training Project for families who want sleep support without judgment. A sleep-deprived parent might start with the crying-it-out episode. Someone curious about the wider cultural lens could begin with the conversation about breastfeeding in literature.
Made for: Suits a parent of a baby or young child who wants to see the studies behind advice on sleep, feeding and nurture, and who distrusts guidance that runs on fear or guilt.
What sets it apart: It checks standard Western advice, from warnings against bedsharing to cry-it-out sleep training, against both the research and the way babies have been cared for across human history. It is also candid about where the evidence is thin rather than contrary.
The Evolutionary Parenting Podcast with Tracy Cassels, PhD focuses on topics and research relevant to parents today. Using developmental psychology, biology, anthropology, and evolution as a basis for all discussion, the podcast explores parenting issues like sleep (including sleep training, co-sleeping, and bedsharing), breastfeeding and feeding, discipline, and more. Tracy interviews both professionals who are in the parenting world and researchers whose research is relevant to today's parents. For parents who want to understand how our children have evolved to develop, how we as parents can help them thrive, and the role of science in all of this.
From baby sleep to autism support, Tracy Cassels asks who wrote the rules you're trying to follow.
