Two studies found that "when the infant is clothed only in a diaper and placed in between the mother or fathers breasts, chest-to-chest [elevated  paternal oxytocin levels were] shown to reduce stress and anxiety in parents after interaction." Discharge
For births that occur in hospitals the WHO recommends a hospital stay of at least 24 hours following an uncomplicated vaginal delivery and 96 hours for a Cesarean section. Looking at length of stay (in 2016) for an uncomplicated delivery around the world shows an average of less that 1 day in Egypt to 6 days in (pre-war) Ukraine. Averages for Australia are  2.8 days and 1.5 days in the UK. While this number is low, two-thirds of  women in the UK have midwife-assisted births and in some cases the mother may choose a hospital setting for birth to be closer to the wide range of assistance available for an emergency situation. However,  women with midwife care may leave the hospital shortly after birth and her midwife will continue her care at her home. In the U.S. the average length of stay has gradually dropped  from 4.1 days in 1970 to a current stay of  2 days. The CDC attributed the drop to the  rise in health care costs, saying  people could not afford to stay in the hospital any longer.
As attitudes began to change, some hospitals offered a "rooming in" option wherein after a period of routine hospital procedures and observation, the infant could be allowed to share the mothers room. As of 2020, rooming in has increasingly become standard practice in maternity wards. Cardinal Movements of birth
Humans are bipedal with an erect stance. The erect posture causes the weight of the abdominal contents to thrust on the pelvic floor, a complex structure which must not only support this weight but allow, in women, three channels to pass through it: the urethra, the vagina and the rectum. The infants head and shoulders must go through a specific sequence of maneuvers in order to pass through the ring of the mothers pelvis. Range of motion and ambulation are typically unaffected during labour and it is encouraged that the mother move to help facilitate progression of labour. The vagina is called a birth canal when the baby enters this passage. Six phases of a typical vertex or cephalic (head-first presentation) delivery:

Engagement of the fetal head in the transverse position. The babys head is facing across the pelvis at one or other of the mothers hips. Descent and flexion of the fetal head. The babies head moves down the birthing canal and tucks its chin on its chest so that the back or crown of its head leads the way through the birth canal. Internal rotation. The fetal head rotates 90 degrees to the occipito-anterior position so that the babys face is towards the mothers rectum.
