To take your baby off your breast, first release the suction by putting your finger in the corner of your baby's mouth between the gums. Don't limit the time you let your baby nurse. This doesn't prevent sore nipples, it just keeps the milk ducts from completely emptying. This can lead to swelling and pain. Applying crushed ice compresses before nursing can ease discomfort.
Some women find that rubbing lanolin or vitamin E oils on their nipples is soothing.
If you use lanolin or vitamin E oils, wash them off before feeding your baby. Call your doctor if you have a red, sore or painful area on your breast, if you have painful engorgement, if you have a fever or if you feel achy. These may be signs of an infection. Make sure your baby is sucking the right way. If the sucking hurts, your baby's mouth may not be positioned correctly.
