What is crowning in labor?

Crowning in labor is the final phase of the second stage of labor when the baby's head becomes visible at the vaginal opening and stays visible between contractions instead of slipping back in. It happens after full cervical dilation to 10 centimeters and after a period of pushing, when the widest diameter of the baby's head has descended through the pelvis and is stretching the vaginal outlet and perineum. Crowning is a critical milestone because it signals that vaginal birth is imminent, usually within a few minutes to half an hour. Healthcare providers can see the top of the baby's head, often with hair visible, and they will usually ask the mother to slow her pushing, pant, or breathe through contractions to allow the perineum to stretch gradually and minimize tearing. The mother typically feels intense pressure, burning, and stinging at this point, known as the ring of fire. Once crowning is achieved, the head is born with the next few pushes, followed quickly by the shoulders and body. Crowning is a normal, expected part of vaginal delivery and indicates the end of labor is near.

Crowning in labor is the stage in the second stage of labor when the baby's head is visible at the vaginal opening and remains visible between contractions, meaning it no longer slips back in after each push. It occurs when the mother has fully dilated to 10 centimeters and has been pushing, and the widest part of the baby's head has passed through the pelvis and is stretching the vaginal opening and perineum to its maximum. Crowning is a key sign that birth is imminent, usually within minutes. It is often accompanied by an intense burning or stinging sensation known as the ring of fire due to stretching of vaginal tissues and nerves. At this point, healthcare providers often instruct the mother to slow down, pant, or give small pushes to allow tissues to stretch gradually and reduce risk of severe tearing. Once crowning occurs, the baby's head is born shortly after, followed by shoulders and body in the next contraction. Crowning is a normal and expected part of vaginal birth and indicates the final moments before the baby is born, often bringing a sense of relief that the end is near.
