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.
Intermenstrual bleeding, previously known as metrorrhagia, is uterine bleeding at irregular intervals, particularly between the expected menstrual periods. It is a cause of vaginal bleeding. In some women, menstrual spotting between periods occurs as a normal and harmless part of ovulation. Some women experience acute mid-cycle abdominal pain around the time of ovulation (sometimes referred to by the German term for this phenomenon, mittelschmerz). This may also occur at the same time as menstrual spotting. The term breakthrough bleeding or breakthrough spotting is usually used for women using hormonal contraceptives, such as IUDs or oral contraceptives, in which it refers to bleeding or spotting between any expected withdrawal bleedings, or bleeding or spotting at any time if none is expected. If spotting continues beyond the first 3-4 cycles of oral contraceptive use, a woman should have her prescription adjusted to a pill containing higher estrogen:progesterone ratio by either increasing the estrogen dose or decreasing the relative progestin dose.Besides the aforementioned physiologic forms, metrorrhagia may also represent abnormal uterine bleeding and be a sign of an underlying disorder, such as hormone imbalance, endometriosis, uterine fibroids, uterine cancer, or vaginal cancer. If the bleeding is repeated and heavy, it can cause significant iron-deficiency anemia. Cause
Intermittent spotting between periods can result from any of numerous reproductive system disorders:

Breakthrough bleeding
Breakthrough bleeding (BTB) is any of various forms of vaginal bleeding, usually referring to mid-cycle bleeding in users of combined oral contraceptives, as attributed to insufficient estrogens. It may also occur with other hormonal contraceptives.
