What is the first stage of birth known as?

The first stage of birth is known as engagement. This stage is crucial as it marks the beginning of labor, where the fetus moves down into the pelvis and its presenting part settles in the pelvic inlet. Engagement typically occurs when the widest part of the baby’s head enters the pelvic cavity, which is a key prerequisite for the subsequent stages of labor.

Understanding engagement is essential for recognizing how the labor process progresses. It indicates that the body is preparing for labor, and once engagement occurs, it sets the stage for descent and eventual delivery. The baby’s position during this stage can significantly affect the labor process and may influence the steps that follow in childbirth, making it a vital concept in obstetrics.
