There is no difference in structure between a baby’s normal labia and an adult’s labia. As they have not yet entered puberty, the ovaries do not secrete estrogen and progesterone cyclically, and the labia have not yet begun to develop. When the secretion of estrogen and progesterone after the labia only began to develop, so the baby’s normal vulva is the labia majora and labia minora are particularly small. Especially pay attention to the local resistance is relatively poor, adults should give good care, keep the vulva clean. Every time after the bowel movement should do a good cleaning, to avoid the possibility of labia adhesion. In addition, if you find the baby localized redness and swelling, and the baby crying always scratching the vulva, it is likely to be caused by local inflammation, it is recommended to go to the hospital for consultation.
