Convenience. Once established, breastfeeding is convenient. It is free and readily available.
Hormonal benefits. Breastfeeding releases hormones that promote maternal fulfillment. Prolactin and oxytocin promote relaxation and feelings of nurturing, love, and attachment. Oxytocin also triggers uterine contractions that help return the uterus to its normal size and decrease post-partum bleeding.
Calorie burn. Breastfeeding burns extra calories and helps some women lose their pregnancy weight.
Delay of menses. Breastfeeding delays the return of menstruation in some women.
Health benefits. Mothers who breastfeed experience reduced rates of breast cancer, ovarian cancer, Type 2 diabetes, rheumatoid arthritis, and cardiovascular disease later in life.
