Quick Answer
Mastitis is breast inflammation that can become an infection when milk does not drain well. AAP guidance on HealthyChildren.org recommends continuing to breastfeed or express milk, using cold compresses, resting, drinking fluids, and taking anti-inflammatory pain medication as directed. Contact your doctor if symptoms last more than 24 hours, worsen, or include fever—antibiotics may be needed.
What Parents Need to Know
Mastitis often starts when an area of the breast does not empty often enough. You may notice a painful, warm, red patch on the breast and feel tired or achy, similar to the flu.
Many nursing parents worry about antibiotics passing into breast milk. AAP guidance reassures that antibiotics commonly used for mastitis generally do not cause problems for the nursing infant. Stopping antibiotics early can raise the risk of repeat infection and scarring that affects future milk production.
Evidence-Based Guidance
AAP guidance describes mastitis symptoms as swelling, warmth, burning, redness or pain, along with fever, flu-like symptoms, or general aches. You should let your doctor know right away if you develop these signs.
Treatment per AAP includes cold compresses and antibiotics when prescribed, plus frequent breastfeeding, rest, plenty of fluids, and anti-inflammatory pain medication. Complete the entire antibiotic course. If you are not feeling better within 72 hours after starting an antibiotic, talk with your provider because another antibiotic or approach may be needed.
AAP guidance is clear: continue breastfeeding or expressing milk during mastitis. Frequent milk removal helps drain the breasts and prevents the infection from worsening. Your baby is not harmed by drinking breast milk during mastitis.
If nursing on the infected breast is too painful, AAP guidance suggests feeding from the other breast and emptying the affected side by nursing, hand expression, or pumping. Avoid overpumping beyond what your baby would normally consume.
CDC breastfeeding special-circumstances guidance reminds nursing parents to consult their physician when interpreting illness information, since individual medical history matters.
Practical Steps
- Nurse or pump frequently on the affected side to keep milk moving.
- Apply cold compresses between feeds for comfort, as AAP guidance suggests.
- Rest and hydrate—recovery takes energy.
- Take prescribed antibiotics for the full course even if you feel better sooner.
- Call your clinician if fever rises, redness spreads, or you do not improve within 72 hours on antibiotics.

MomAI Agent on momaiagent.com helps exhausted nursing parents stay organized during mastitis recovery. Mom AI Agent can log which breast was nursed or pumped, track fever readings, and save AAP symptom checklists to share at your follow-up visit—practical tracking, not a substitute for medical care.
Safety Considerations
- Do not stop breastfeeding abruptly during mastitis unless your clinician directs you—milk stasis can worsen inflammation.
- Watch for spreading redness, worsening pain, or high fever that does not improve with treatment.
- Ask before taking any new medication, including herbal remedies, while breastfeeding.
- Seek urgent care if you have shaking chills, confusion, or feel severely ill.
When to Contact a Clinician
Contact your doctor or lactation consultant if:
- Mastitis symptoms last more than 24 hours or worsen
- You develop fever or flu-like aches
- You are not improving 72 hours after starting antibiotics
- You have trouble latching or milk supply drops sharply on one side
Seek emergency care for difficulty breathing, chest pain, or signs of severe infection.
The Bottom Line
AAP guidance supports continuing to breastfeed or express milk, resting, and using clinician-directed treatment—including antibiotics when needed—to resolve mastitis and protect long-term milk production.
