![]() ![]() This movement is also known as restitution. External Rotation/Restitution: Once the baby’s head is born, the baby must rotate from facing head down to either right or left to fit the shoulders around and under the mother’s pubic arch.The baby’s head, face, and chin appear outside the mother. The baby’s head must extend back to accommodate the upward curvature of the birth canal. Extension: Usually, the back of the baby’s head is against the mother’s pubic bone as it passes through the vaginal opening.Usually, the baby faces down toward the mother’s spine, although sometimes the baby faces the mother’s pubic bone. The baby’s head rotates to accommodate these changes in the diameter of the mother’s pelvis. Now, with the baby reaching the mother’s pelvic floor, the widest diameter of the mother’s pelvis is from front to back. Internal Rotation: When the baby’s head enters the mother’s pelvis (engagement), the widest diameter of the mother’s pelvis is from right to left.As the baby’s head meets resistance from the soft tissue of the mother’s pelvis, the baby’s head flexes downward so that the baby’s chin touches the baby’s chest. Flexion: Flexion occurs during descent.Descent: Descent occurs as the baby’s head moves deeper into the mother’s pelvic cavity. ![]() Engagement may occur toward the end of pregnancy or during labor. The entry point of the mother’s pelvis (pelvic inlet) has its widest diameter from right to left. Engagement: Engagement occurs when the widest part of the baby’s head (the biparietal diameter, measured from ear to ear) enters the mother’s pelvis.These movements work to allow the smallest diameter of the baby’s head to pass through the mother’s pelvis. There are seven cardinal movements a baby makes while attempting to get into the best position for birth. ![]()
