A 4-week postpartum patient with mastitis asks the nurse if she can continue to breastfeed her infant. After assessing her symptoms and understanding her concerns, what is the nurse's best evidence-based response?

Current evidence-based guidelines from organizations such as the Academy of Breastfeeding Medicine and the World Health Organization strongly recommend that a mother with mastitis continue breastfeeding from both breasts, with particular emphasis on frequent emptying of the affected breast. Mastitis is an inflammatory condition of the breast tissue, most commonly caused by milk stasis and, in some cases, bacterial infection (often Staphylococcus aureus). The primary treatment principle is to ensure complete and frequent milk drainage, which reduces the buildup of pressure, inflammatory mediators, and bacteria within the ducts. Feeding frequently from the affected breast — especially starting feeds on that side — is the most effective way to clear the infection, reduce pain, and prevent progression to abscess formation. The infant is not harmed by the infected milk because the bacteria and inflammatory proteins are destroyed by the infant's digestive system, and the milk itself retains its nutritional and immunological value. Stopping breastfeeding abruptly or pumping and discarding milk can worsen engorgement and accelerate abscess formation. Breastfeeding from only the unaffected breast fails to drain the infected side and increases the risk of complications. Over-the-counter stimulant laxatives or waiting until antibiotics are complete before resuming feeding are not recommended strategies. Antibiotic therapy supports but does not replace the need for continued, frequent milk removal.
