The main purpose of putting your hand in to feel the position of the fetus during childbirth is to assist the mother in labor, adjust the position of the fetus, and control the speed of delivery, etc., but the specific situation varies from person to person. When a woman is in labor, midwives and nurses need to guide the woman to push, conduct vaginal examination to facilitate the assessment of the fetal condition, and if the fetal position is not suitable for delivery, the fetal position needs to be adjusted manually to facilitate delivery. It is also to control the speed of delivery of the fetal head, to protect the perineum to a certain extent, to allow the fetal head to pass through the vaginal opening in the most appropriate way, and to alleviate the degree of perineal tearing. In addition to this, if the woman is unable to deliver the placenta on her own after the delivery of the fetus, a hand is usually inserted into the uterus to help the woman deliver the placenta.
