The dilation stage of labor consists of how many phases?

The dilation stage of labor is a crucial part of the labor process, characterized by several distinct phases that represent the gradual opening of the cervix in preparation for childbirth. This stage is typically divided into four phases:

1. Early Labor (Latent Phase): During this initial phase, the cervix dilates from 0 to about 3 centimeters. Contractions begin and are often irregular. This phase can last for hours or even days.

2. Active Labor: In this phase, the cervix dilates from 4 to 7 centimeters. Contractions become more regular, stronger, and closer together, indicating that labor is progressing more robustly.

3. Transition Phase: This is when the cervix dilates from 8 to 10 centimeters. Contractions are typically very strong and frequent. This phase can be quite intense and is often considered the most challenging part of the dilation stage.

4. Complete Dilation: At this point, the cervix has reached maximum dilation of 10 centimeters, allowing for the baby to move down the birth canal.

Understanding these four distinct phases is important for doulas and birthing professionals, as each phase can have different physical and emotional characteristics, and may
