Pregnancy to parenting on Instagram: "The occipito-anterior (OA) position means your baby’s head is down, with the back of the head (the occiput) facing the front of your pelvis and the baby’s face toward your spine. This is considered the most ideal position for birth, as it allows the baby to align perfectly with the shape of the birth canal. In the OA position, the baby’s chin is tucked and the smallest diameter of the head leads the way, helping labor progress more smoothly and efficiently.
