yes you can use an antifungal cream but use it after you feed your baby. wipe your nipples before you nurse. if you have yeast on your breasts then you baby most likely has thrush. if the pediatrician prescribed a thrush medicine for the baby like mycostatin oral suspension you can use this on your nipple as well (and you don't have to wipe if off before or after nursing).
my baby gave me thrush on my nipple could i use clotrimazole to treat it?
