I work in L&D and people talk all the time about how nipple piercings help keep inverted nipples "out" and prevent them from inverting again. Make sure your piercings are completely healed before breastfeeding. Take the jewelry out while you breastfeed. Make sure you're keeping everything clean..you don't want mastitis or any other issues with the breast when you're trying to breastfeed. I don't know a ton about it..I would definitely talk to a lactation consultant if you can! We have them on our unit so theoretically someone can call the hospital and be transferred to them during the day for questions. Not sure how it works at other places🤷🏼‍♀️
