Breastfeeding does not hurt. There may be some tenderness at first, but it should gradually go away as the days go by. Your breasts and nipples are designed to deliver milk to your baby. When your baby is breastfeeding effectively, it should be calming and comfortable for both of you. If breastfeeding becomes painful for you, seek help from someone who is knowledgeable about breastfeeding.
To minimize soreness, your baby’s mouth should be wide open, with as much of the areola (the darker area around the nipple) as far back into his or her mouth as possible. The baby should never nurse on the nipple only. If it hurts, take the baby off of your breast and try again. The baby may not be latched on right. Break your baby’s suction to your breast by gently placing your finger in the corner of his/her mouth, and re-position your baby.
