Midwifery is a health care or medical profession, in which it deals with care to childbearing women during their pregnancy, labour and birth, and during the postpartum period (including care of the new-born), includes assisting with breastfeeding, besides sexual and reproductive health of women throughout their lives. A practitioner of midwifery is known as a midwife, which they strive to help women to have a healthy pregnancy and natural birth experience. Midwifery practice throughout the world remains as culturally established, and the specific standards and education for midwives varies by country. When a pregnant woman requires more care beyond the midwife's practice, they refer women related to obstetricians or perinatologists who are medical specialists in complications related to pregnancy and birth, includes surgical and instrumental deliveries.
