Does having menstrual periods after childbirth affect breastfeeding?
In general, the return of menstruation after childbirth does not affect breastfeeding. The detailed explanation is as follows:
The resumption of menstrual cycles postpartum does not immediately impact the quality or quantity of breast milk. The composition of breast milk is primarily determined by the mother's nutritional status, rather than her menstrual cycle. Many women continue breastfeeding successfully after their periods return, with no adverse effects on their babies' growth and development. This is because the body can simultaneously meet the physiological demands of both menstruation and lactation—milk production by the mammary glands and the menstrual cycle are two relatively independent processes. Additionally, some women may notice a temporary decrease in milk supply during their period, but this does not indicate a decline in milk quality. It may be due to hormonal fluctuations during menstruation and is usually short-lived. Therefore, the return of menstruation after childbirth generally has no significant effect on breastfeeding.
During menstruation, a woman's nutritional needs may increase. To ensure adequate milk quality and quantity, mothers should enhance their nutrition by consuming more iron-rich and high-protein foods, such as fish and chicken.
