Ep. 392: Nature vs. Nurture: Unlocking the Secrets of Parent-Child Attachment with Dr. Rocio Zunini

What actually shapes the way we connect with our babies? Our biology or our environment? In this episode of The Birth Lounge Podcast, HeHe sits down with neuroscientist Dr. Rocio Zunini to unpack the wildly fascinating science of parenthood and attachment styles.

You’ll learn how your brain literally changes during pregnancy and parenting (yes, your brain rewires itself!), why nurturing is far more powerful than we ever realized, and how those early interactions shape lifelong emotional regulation and resilience.

Dr. Zunini breaks down groundbreaking research on how nurturing behavior in animals translates to humans, from secure to anxious, avoidant, and disorganized attachment styles and what that means for how we show up as parents.

They also dig into how mothers’ and fathers’ brains adapt differently, the critical role of “allo parents” (those loving caregivers beyond mom and dad), and how awareness and mindful connection can actually rewrite generational patterns.

If you’ve ever wondered how to raise emotionally secure, confident kiddos or how your own upbringing plays a role in the parent you’re becoming, this one’s a must-listen.
