About this episode

This episode discusses the importance of pelvic biomechanics and movement during labor with expert Brittany Sharpe McCollum.

The way we move during labor shapes far more than our comfort. It helps determine how a baby navigates through the pelvis, and whether a birth can unfold with fewer interventions! In this replay episode, Dr. Rebecca Dekker talks with Brittany Sharpe McCollum, a childbirth educator, doula, lactation counselor, and pelvic biomechanics educator. Brittany explains how the bones of the pelvis move during labor, why that movement matters for fetal positioning, and how everyone can benefit from intentional position changes during labor-- whether you're planning an unmedicated birth or not! They explore the three planes of the pelvis, why opening the pelvic inlet and outlet require opposite movements, and how to match specific positions to where the baby is located in the pelvis. Brittany also shares her 5-4-3 rule for position changes, practical tips for inductions and epidurals, the power of asymmetrical positioning, and why movement is one of the few birth tools that carries benefit without risk.
