The feminist movement in the United States openly and actively supported the use of twilight sleep, which was introduced to the country in 1914. Some physicians, many of whom had been using painkillers for the past fifty years, including opium, cocaine, and quinine, embraced the new drug. Others were rightfully hesitant. Caesarean sections
There are many conflicting stories of the first successful cesarean section (or C-section) in which both mother and baby survived. It is, however, known that the procedure had been attempted for hundreds of years before it became accepted in the beginning of the twentieth century. While forceps have gone through periods of high popularity, today they are only used in approximately 10 percent of deliveries. The  c-section has become the more popular solution for difficult deliveries. In 2005, one-third of babies were born via C-section. Historically, surgical delivery was a last-resort method of extracting a baby from its deceased or dying mother but today caesarean delivery on maternal request is a medically unnecessary caesarean section, where the infant is born by a caesarean section requested by the parent even though there is not a medical indication to have the surgery. Natural childbirth
The reemergence of "natural childbirth" began in Europe and was adopted by some in the US as early as the late 1940s. Early supporters believed that the drugs used during deliveries interfered with "happy childbirth" and could negatively impact the newborns "emotional wellbeing".
This is referred to as "delivery en caul". Complete expulsion of the baby signals the successful completion of the second stage of labour. Some babies, especially preterm infants, are born covered with a waxy or cheese-like white substance called vernix. It is thought to have some protective roles during fetal development and for a few hours after birth. The second stage varies from one woman to another. In first labours, birth is usually completed within three hours whereas in subsequent
labours, birth is usually completed within two hours. Second-stage labours longer than three hours are associated with declining rates of spontaneous vaginal delivery and increasing rates of infection, perineal tears, and obstetric haemorrhage, as well as the need for intensive care of the neonate. Third stage: placenta delivery
The period from just after the fetus is expelled until just after the placenta is expelled is called the third stage of labour or the involution stage. Placental expulsion begins as a physiological separation from the wall of the uterus. The average time from delivery of the baby until complete expulsion of the placenta is estimated to be 10–12 minutes dependent on whether active or expectant management is employed. In as many as 3% of all vaginal deliveries, the duration of the third stage is longer than 30 minutes and raises concern for retained placenta.Placental expulsion can be managed actively or it can be managed expectantly, allowing the placenta to be expelled without medical assistance.
