Breastfeeding? Cracked Nipples? It happens. Typically cracked nipples are a result of a poor latch. Correcting your latch will help significantly. Healing the cracked nipples requires BREAST MILK and AIR (of course a little sunshine would be nice too)! Yes, just express some breast milk and coat your nipples with it. Leave your bra flaps down and let air dry the breast milk on your nipples. Repeat often.
Keep Breastfeeding! Keep putting baby to breast but be hyper vigilant about the latch and your posture. If the pain is too much, pump and take a break through the night. By morning your nipples will be healed enough to get right back at it!
