Labor stages refer to the process of childbirth, which is typically divided into three main phases. The first stage involves the onset of contractions and the gradual dilation of the cervix, preparing for delivery. This stage can last several hours to days, especially for first-time mothers. The second stage begins when the cervix is fully dilated, allowing the baby to move through the birth canal. This stage ends with the delivery of the baby. The third stage involves the delivery of the placenta, which usually occurs shortly after the baby is born. Each stage is crucial for a safe and healthy childbirth experience.
