Neonatal menstruation is the bleeding that some newborn female babies experience a few days after birth for around 3-4 days. Another name for it is false menses. Its cause is the sudden drop-off in the mother’s estrogens after birth. Few people know about this phenomenon as it is not a popular topic, but it is an important one in the case of new parents and the safety of the babies as sometimes unawareness can cause a misunderstanding about whether it is some infection or the false menses.
False Menses is a natural response of the baby’s body to the sudden drop in the levels of estrogen it had received from the mother’s body in the womb. When she is born, the drop in hormonal levels triggers the shedding of the inner uterine layer, hence resulting in vaginal bleeding.
