Midwifery care is a crucial part of maternal and child health care, especially for mothers who have just given birth. The postpartum period extends from a few hours after the placenta is delivered to 6 weeks or 42 days. Insufficient breast milk production can lead to insufficient supply to the baby. Decreased breast milk production in the first few days after delivery can be caused by insufficient stimulation of the hormones prolactin and oxytocin. Therefore, midwifery care for postpartum mothers, including oxytocin massage, is essential. The method used is descriptive. The report is a case study, involving a postpartum mother at Dr. H. Jusuf SK Tarakan Regional Hospital. Results obtained during comprehensive care revealed the patient complained of insufficient breast milk production. Midwives provide implementation of midwifery care by administering oxytocin massage. The conclusion is that comprehensive midwifery care has been provided starting from pregnancy, childbirth, postpartum, neonates, newborns so that mothers avoid complications and are able to provide smooth breastfeeding to their babies after being given oxytocin massage.
