What wipes do you use to clean your breasts before pumping or feeding baby?

Nothing. I don't clean my breasts before pumping or feeding my baby as there's no need to. If my nipples are sore, I apply breastmilk and let it air-dry. I think a lot of new mothers worry unnecessarily. It's not dirty and milk is sterile. If you're worried, just wipe it with a clean towel or wet wipe. My baby has never fallen sick from breastfeeding. In fact, she has gone through her immunizations without fever or diarrhoea.
