What if the very act of nurturing your child could rewire your traumatized brain? Today I explore how parenting changes your brain with neuroscientist and author Greer Kirshenbaum. As someone who couldn't co-sleep because of my PTSD flashbacks, I was deeply moved by what Greer revealed about the science of parental transformation.

We discuss why some parents feel disconnected from their bodies and struggle with physical closeness, yet still can create secure attachments with their babies. Greer shares surprising research about what happens in both parent and baby brains during those early years, and why your perceived "failures" as a parent might actually be completely irrelevant to your child.

We also tackle the tough questions—what if you never learned how to nurture because you weren't nurtured yourself? What if trauma makes traditional bonding advice impossible to follow? This conversation gave me a completely new perspective on my own parenting journey and the healing that happened without me even realizing it.

Topics covered on How Parenting Changes Your Brain:

1. What specific brain regions transform when you become a parent, and why can scientists identify parents just by looking at 70-year-old brains?
2. How does parenting change your brain differently for birthing parents versus non-birthing parents?
3. Can nurturing your baby actually heal your own childhood trauma and create the secure attachment you never had?
4. What if you can't co-sleep or struggle with physical touch due to PTSD—are there alternatives that still foster connection?
5. Why do babies in the NICU still recognize their parents, and what simple voice recording technique helped me bond with my medically fragile newborn?
6. If you never received nurturing as a child, how can you learn to parent differently without an internal working model?
7. How does parenting change your brain to see your body differently—why did I finally love my body only after becoming a mother?
8. Why does your baby think you're perfect even when you hate your body or feel like a failure?
