It is best not to breastfeed when the nipple is broken, because after the nipple is broken, external bacteria will enter the milk ducts along the broken opening, thus causing inflammation of the mammary glands. In this case, it is necessary to strengthen the cleaning of the broken nipple to avoid the growth of a larger number of bacteria, which will cause acute suppurative infections of the mammary glands. Although normal breastfeeding is not possible, it is recommended that the milk on the affected side be completely sucked out through a breast pump to avoid a large amount of milk stagnation, which creates favorable conditions for bacterial growth. Therefore, under the premise of milk emptying, keeping the nipple clean is an important way to avoid the occurrence of mastitis. Although the affected side of the patient is unable to breastfeed, the healthy side is recommended to breastfeed normally, and the breastfeeding on the healthy side can not only provide enough energy and nutrition for the baby, but also effectively avoid the accumulation of milk in the healthy side of the breast.
