Mastitis neonatorum or infections of the breast tissue may occur during the newborn period. It is often secondary to squeezing the breast to remove the milk because of maternal oestrogen effect by untrained "Dhais". Treatment includes antibiotics. If an absecess occurs, needle aspiration should be performed. Surgical drainage should only be considered when needle aspiration is unsuccessful because an operation may damage the breast bud and result in reduction of adult breast size.
