The dilation stage of labor begins at which event?

Explanation:
Dilation begins with the onset of true labor—the moment regular, progressive contractions start that cause the cervix to begin to dilate and efface. From there, the cervix opens from 0 cm to 10 cm, marking the first stage of labor. This stage includes an early part where dilation begins and a later part with more rapid dilation as contractions strengthen. The birth of the baby occurs in the second stage, and placental delivery happens in the third stage; simply ending contractions isn’t the boundary that defines the start of this stage.
