If the baby has sore nipples after breastfeeding, it may be caused by the inflammation of the nipple after being chewed. It is also possible to apply hot towels to the nipples to promote local blood circulation and the dissipation and absorption of inflammation, which is beneficial to the relief of nipple pain. Generally after systematic treatment of nipple inflammation, there are about 7 days to gradually return to normal, pay attention to the good habit of letting the baby eat milk correctly, do not let the baby chew the nipple with teeth, otherwise inflammation is likely to occur again, if the baby is old enough, but also gradually wean the child.
