I'm an RN & work with moms & babies, I know about this.If you're not going to breastfeed your baby, avoid any touching or stimulating breasts.Don't let water in shower spray on them, just wipe gently/quick rinse.Take Tylenol(acetaminophen) for discomfort of engorged breasts
if needed. Only ice, no heat! Wear a snug bra (NO UNDERWIRE) 24/7 until milk has dried up & get a head of green cabbage, remove several & put in freezer. Put a cabbage leaf around breasts in the bra frequently.When it's no longer cold, remove it, rinse it & return to freezer.Cabbage will help more than anything I've ever seen. Contact your doctor or midwife if pain worsens or any red areas appear on breasts.
