I used this constantly when I was breastfeeding my newborn. My nipples were SO sore, chapped and even a little bleeding. I used in combination with coconut oil. I like that it's not harmful to baby so you don't have to clean off your nipple before you feed, and seeing as how you feed almost every hour, that could get really annoying! Honestly, my nipples didn't really heal until I stopped breastfeeding for a couple days and pumped instead - still applying the lanolin. I had to give it time to work!
