Sore or damaged nipples are common in breastfeeding mums but are a sign that something is wrong. If you have sore nipples there should be a reason for why they are sore.
The most common reason is an incorrect latch. If you are certain that your latch is correct but your nipples continue to be sore or damaged, you should seek help.
The best nipple cream to use in-between feeds to keep the nipples moist and healing is plain coconut oil.
