What causes a breast infection/mastitis?

A common cause of a breast infection is normal bacteria from your skin entering the milk ducts through a crack on, or other damage to, your nipple.  Most likely this crack is from a shallow latch. Sometimes a breast infection follows a plugged duct and can be caused by the same things: irregular feeding patterns or missed feedings, tight clothing (bras, bathing suits, etc.), pressure on the breast from a baby carrier, heavy purse or diaper bag, sleeping on one’s stomach and unusual stress or fatigue.

To encourage, promote and provide breastfeeding, chest feeding and human milk feeding support and educational opportunities as an important contribution to the health of children, families and society
