The claim
「A newborn girl’s pseudo-menstruation is a problem needing treatment」
Verdict
MythA small amount of blood-tinged vaginal discharge in the first days is a normal withdrawal response to maternal oestrogen, usually resolving in 2–7 days. Just clean normally — no intervention needed. Seek review if bleeding is heavy, prolonged, or comes with fever.
