Hepatitis B mothers with broken nipples that are not bleeding are not advised to breastfeed, they can express milk from the affected side to maintain lactation and then breastfeed after the broken nipples have completely healed. Hepatitis B virus is transmitted from mother to child in three main ways, including intrauterine infection, transmission during labor, and postnatal transmission. The main risk factor is the level of hepatitis B virus in the mother’s blood, while breast milk is almost free of hepatitis B virus. Breastfeeding does not increase the chance of mother-to-child transmission of hepatitis B virus, but although there is no blood in the broken nipple, breastfeeding is not recommended in order to avoid the bleeding caused by breastfeeding. It is recommended not to breastfeed on the affected side, but to use the good side to breastfeed, and to wait until the skin is completely healed before breastfeeding normally.
