The white substance in the private parts of a newborn baby girl is generally a normal vaginal discharge, which is mainly stimulated by maternal estrogen. The specific reason is that the endometrium and vaginal mucosa of a fetus in the womb are stimulated by the mother’s estrogen. The sudden interruption of estrogen supply from the mother after the birth of a newborn baby will cause the newborn girl to shed the endometrium and the proliferated vaginal mucosa, forming a temporary physiological phenomenon similar to leukorrhea and menstruation in adults. Parents are advised to wash the vulva more often, and the white material will disappear naturally after cleaning. When cleaning, pay attention to the top to bottom and front to back, only the external vaginal opening should be cleaned and dried in time after cleaning, so that the pubic area is always clean and dry. Note 1: Baby girls’ reproductive organs are more susceptible to infection, so care is more difficult and requires more careful and patient parental care. 2: After a baby girl’s bowel movement, pay attention to the direction of wiping, from front to back, to prevent dirt from entering the vagina. After urinating, wipe clean and keep the area dry. 3. Baby girls should also pay attention to what they wear, and try not to wear crotchless pants to avoid direct contact with airborne bacteria. Use diapers to change them regularly, etc.
