A monthly nurse is a woman who looks after a mother and her baby during the postpartum or postnatal period. The phrase is now largely obsolete, but the job continues under other names and conditions worldwide. In the past, it was customary for women to rest in bed or at home for a prolonged period after childbirth. Typically, their female relatives, such as their mother or mother-in-law, would provide care, or wealthy families would hire a monthly nurse. This period, known as confinement or lying-in, would end with the mother's reintroduction to the community during a Christian ceremony called the churching of women.

Conversely, they may work in a central setting, where the new mothers come after they leave the hospital. In Korea, these workers are called Sanhujorisa, and the centers started up in the late 1990s. History Historically, the delivery of babies and care of the mothers was inherited from mother to daughter, with the daughter spending many years as the pupil or apprentice. The Church supported that by a system of licensing, which required midwives to swear to some rules regarding contraception, abortion, and concealment of births and also to deliver the newborn infants for baptism or, in extreme cases, to perform the ceremony themselves. In the mid-18th century, the legal status of midwives was withdrawn, and the surgeon's responsibility for delivery was vested. This raised the question of who would take care of the baby after birth. It was generally thought that the best person to look after her baby was a woman who had had
