This phenomenon is normal and does not require special treatment. It is recommended to check the nipple surface for the presence of a rupture, because the newborn may suck the nipple with too much force and cause a rupture in the nipple surface and nipple pain. When the nipple is broken, pathogenic microorganisms can invade and cause mastitis, which not only affects the health of the pregnant woman, but also leads to diseases in the baby’s mouth when the baby is attracted to the nipple. In the postpartum breastfeeding process, if you find any abnormalities in the breast, it is recommended to go to the mammography department for appropriate laboratory tests and examinations to avoid delays in the diagnosis and treatment of the disease, and women should pay attention to the cleanliness of the breast during breastfeeding, and wash it with warm water every day.
