The perineum and cervix are further flattened and the head may be felt vaginally. [2] Head engagement is known colloquially as the baby drop, and in natural medicine as the lightening because of the release of pressure on the upper abdomen and renewed ease in breathing. However, it severely reduces bladder capacity resulting in a need to void ...
The fetal head then continues descent into the pelvis, below the pubic arch and out through the vaginal opening. This is assisted by the additional maternal efforts of pushing, or bearing down, similar to defecation. The appearance of the fetal head at the vaginal opening is termed crowning. At this point, the mother will feel an intense ...

The position on the baby's head is checked. The fetal head is then rotated to the occiput anterior position if it is not already in that position. An episiotomy may be performed if necessary. The baby is then delivered with gentle (maximum 30 lb f or 130 Newton [7]) traction in the axis of the pelvis. [8] [page needed]
Only a comparatively small part of the head at term is represented by the face. The rest of the head is composed of the firm skull, which is made up of two frontal, two parietal, and two temporal bones, along with the upper portion of the occipital bone and the wings of the sphenoid. These bones are separated by membranous spaces, or sutures.
From that point, pressure from the presenting part (head in vertex births or bottom in breech births), along with uterine contractions, will dilate the cervix to 10 centimeters, which is "complete." Cervical dilation is accompanied by effacement, the thinning of the cervix. General guidelines for cervical dilation: Latent phase: 0–3 centimeters

Second stage of labor starts when the cervix is dilated to 10 cm and finishes with the birth of the baby. This stage is characterized by strong contractions and active pushing by the mother. It can last from 20 minutes to 2 hours. [16] Third stage of labor starts after the birth of the baby and is finished when the placenta is delivered. [15]
