The right answer to this question is second stage. The second stage is when the head of the newborn starts to be seen at the vaginal opening. The first stage of labor is when the cervix first starts to dilate. The third stage of labor is when the baby together with its placenta are already delivered.
The fourth stage or the last stage of labor allows both the mother and the baby to recover. There are some mothers who take more time to recover because their organs are still trying to process that they are not pregnant anymore. Take note that the recovery period will be different for all.
Second stage- crowing, which occurs when the newborns head or presenting part appears at the vaginal opening, occurs during the second stage of labor. During the first stage of labor, cervical dilation and effacement occur. During the third stage of labor, the newborn and placenta are delivered. The fourth stage of labor lasts from 1 to 4 hours after birth, during which time the mother and newborn recover from the physical process of birth and the mothers organs undergo the initial readjustment to the nonpregnant state.
