Most complaints of sore nipples, engorged breast, pain when breastfeeding and eventual mastitis or breast abscess have to do with improper attachment of the baby to the breast. Painful breasts mostly has to do with the baby sucking or chewing on the nipple, painful for the mother and frustrating for the baby.

For a successful and painless breastfeeding session, the whole of the nipple and majority of the areola (dark part) must be in the baby's mouth. Sit comfortably and let baby come to meet your breast and not you slouching to meet the baby. Additionally, always alternate the breasts between feeds. Let one breast empty first before switching to another.

And if you still feel you are not putting baby rightly on the breast, complain at the hospital so as to be directed.

Take her to see a burns and plastic surgeon. They will be of help in cases like this.

Kindly see a doctor to know why the baby has the sores in the mouth in the first place. The most important thing to do is to treat the underlying cause of the sores itself and not just focusing on the sores.
