Hello,
First time mom here and breastfeeding! Baby is 2 days old and is latching fine and eating great! The only issue is how much it hurts! When will it begin to feel less painful? The other problem is my left nipple has always been sensitive to touch and now it's really an issue in breastfeeding.
