REPLAY: EBB 196 - Pelvic Biomechanics and Movement in Labor with Brittany Sharpe McCollum

Pelvic biomechanics and fetal positioning play a critical role in facilitating labor, yet these concepts are often overlooked in standard maternity care. Movement during labor—even for those with epidurals—helps the baby navigate the three planes of the pelvis: the inlet, mid-pelvis, and outlet. Brittany Sharpe McCollum, a specialist in holistic birth services, advocates for the "5-4-3 rule," which encourages changing positions every five contractions using four basic postures and three specific techniques: thigh rotation, pelvic tilts, and asymmetry. These movements create necessary space for the baby to descend and rotate, reducing the likelihood of labor stalls or unnecessary interventions. Practicing these positions during pregnancy builds essential muscle memory, allowing the birthing person to bypass the "thinking brain" and rely on instinctive movements that promote a smoother, more autonomous birth experience.
