After internal rotation is complete, the baby's head passes through the pelvis and a short rest occurs when the baby's neck is under the mother's pubic arch. Then extension of the baby's head and neck occur – the neck extends, so the chin is no longer pressed against the baby's chest, and the top of the head, face and chin are born (Figure 1.3, diagrams 4 and 5).
