You need to apply nipple cream or breast milk and air dry to allow faster healing. You need to pump to avoid engorgement but you can massage and apply hot compress to soften your breast. You might want to add a little bit more water to the formula if it’s giving your baby constipation.
Do apply nipple cream to take care of it. In the meantime, continue to pump else it might get engorged. Can try feeding expressed breastmilk for the moment if ur nipple is still in pain.
Please make sure her latch is correct as i had same issues. I saw a lactation consultant and it was solved instantly!
Can speak to lactation consultant ask for advice
