Yes, you can usually keep breastfeeding if you have mastitis, including from the affected breast. Mastitis alone is not a reason to throw away your milk. Feed according to your baby’s needs, avoid extra pumping to “empty” the breast, and get medical advice if you are worsening or not improving. An open infected wound, drainage near the nipple, or a premature or medically vulnerable baby needs an individual feeding plan.
Get emergency help for confusion, slurred speech, severe breathing difficulty, collapse, or blue, grey or blotchy skin while you are unwell. Use 911 in the United States or your local emergency number. Do not wait for a feeding appointment if you think something is seriously wrong.
I would separate two questions straight away: “Can my baby have this milk?” and “What care does my breast need?” In most cases, continuing to feed is possible while you get help for the pain and inflammation. You do not have to choose between looking after yourself and keeping your baby fed.
The next feed, without extra pressure
Usually continue: offer feeds in response to your baby’s needs, including the affected side if manageable.
Do not force: avoid repeated pumping, deep massage or painful attempts to extract more milk.
Get support: ask about worsening symptoms, difficult milk transfer, medicines, and any wound or drain near the feeding area.
Keep an eye on both of you: your symptoms matter, and so do your baby’s feeding, alertness and wet diapers.
What mastitis means for your milk
Mastitis describes breast inflammation. It can involve a painful, swollen or hot area, sometimes with fever and flu-like symptoms. Some cases involve bacterial infection; symptoms alone do not let you decide which treatment you need. Redness can also be harder to notice on darker skin, so pay attention to pain, warmth, swelling and how you feel.
The NHS mastitis guidance recommends continuing breastfeeding. The Academy of Breastfeeding Medicine’s mastitis protocol also supports continued feeding and advises against routine expressing and discarding solely because of bacterial mastitis.
That does not mean every breast symptom can be managed at home. It means the feeding decision and the treatment decision are related but distinct. A clinician may recommend medicine, an examination or a scan while still supporting breastfeeding.
If someone has told you to stop, ask what specific finding or medicine makes stopping necessary, which breast the advice applies to, and when the plan will be reviewed. Follow an individual plan from the team treating you and your baby. A general article cannot override a concern they have actually assessed.
When to call instead of waiting for the next feed
Seek prompt medical advice if pain, swelling or feeling unwell is worsening, or if you are concerned about a breast lump or abscess. The NHS advises review when symptoms have not improved after 12 to 24 hours of home care, or after 48 hours on antibiotics. Those are reassessment points, not instructions to wait through a rapid decline.
Tell the clinician when symptoms began, whether you have a measured temperature, which area hurts, and whether feeding or expressing is working. If you have already started treatment, have the medicine name and start time ready. “I started it yesterday evening and feel worse today” is useful information even without a perfect symptom diary.
The NHS sepsis guidance treats confusion, breathing changes and serious illness as urgent warning signs. You do not need to work out whether mastitis is the cause before getting emergency help. Have another adult look after your baby while help is arranged if possible.
A useful phone note
Started: when the pain, swelling or fever began.
Changed: better, unchanged or worse since then.
Feeding: whether your baby can latch and swallow, or milk can be expressed without forcing.
Treatment: medicines, doses already prescribed and when you started them.
Special circumstances: a wound, drain, previous abscess, premature baby or other medical needs.
Continue ordinary feeding, not a breast-emptying project
“Keep breastfeeding” can sound as though you should put your baby on the sore side again and again until the lump disappears. That is not the goal. The ABM protocol recommends feeding according to the baby’s needs rather than trying to empty the breasts.
Extra milk removal can encourage more production and worsen the cycle of swelling. If you normally breastfeed directly, adding a long pumping session after every feed is not a routine mastitis treatment. A breast feeling different from the other one is not, by itself, a reason to keep extracting milk.
If you exclusively pump, do not abruptly abandon the milk-removal plan your baby depends on. Ask for help keeping expression appropriate to their usual needs, with comfortable suction and a suitable flange fit. More suction, more minutes and a larger bottle total are not reliable signs of better care.
I would make the next decision small: offer the next needed feed, notice whether milk transfer is comfortable enough, and arrange help for what is not working. You are not trying to win a contest against a stubborn patch of breast tissue.
What if the sore side is too painful or milk will not flow?
You do not have to force your baby to stay on a painful breast. The NHS suggests hand expressing enough milk for your baby’s needs if direct feeding is too painful or the baby will not take the affected side. Ask a breastfeeding specialist to look at attachment, positioning and what you are feeling.
There is an important limit: if marked swelling prevents milk from being removed, repeated painful attempts are not useful. ABM describes situations where feeding from the unaffected side temporarily is appropriate while the inflammation settles. Get an individual plan for the affected breast and for ensuring your baby receives enough milk.
Tell the clinician if neither side is providing a workable feed, you cannot express enough, or your baby keeps refusing. The plan may include expressed milk or another appropriate feed while the cause is addressed. Do not leave a hungry or poorly feeding baby waiting for the sore breast to cooperate.
If you try hand expression, use a gentle technique and a suitable clean collection container. Stop forcing a technique that hurts. The purpose is meeting a feeding or comfort need, not repeatedly testing how much you can squeeze out.
Cooling and comfort: keep the treatment gentle
A cool cloth is a simple place to start for comfort. The NHS suggests a cold compress for about ten minutes at a time, as often as hourly. Protect your skin, and stop if the cold is uncomfortable. A specialist product is not required to try that basic measure.
A comfortable supportive bra can help without pressing hard on the sore area. Rest is also part of the plan. In practical terms, that may mean someone else brings your water, prepares food or handles the diaper change rather than asking you to keep getting up between feeds.
Do not knead a lump, use a vibrating device to break it up or increase pump suction to pull it out. ABM warns against deep massage and describes how tissue trauma can worsen inflammation. It also advises against salt soaks and topical remedies used as mastitis treatments.
Heat is not a requirement for clearing mastitis. Prolonged or intense heat may worsen swelling. If your own clinician suggests a brief comfort measure, ask how to use it; do not turn that into repeated hot compresses plus extra pumping.
Treatment and feeding come first
Make the evening easier to hand over
For information about ordinary bedtime routines and baby sleep schedules, visit SleepBaby.org to read the current SleepBaby.org Method offer.
When you are sore and unwell, I would make the evening smaller: keep the feeding plan clear, ask another adult to handle the jobs they can, and keep the number for medical advice close. Rest matters, but a sleep routine does not treat mastitis or decide how much milk your baby needs. Do not postpone care to work on bedtime.
Once your medical and feeding needs are covered, you may have a separate question about your household’s ordinary evenings. The SleepBaby.org Method homepage describes information about bedtime routines and baby sleep schedules. You can read the current offer there and decide whether it fits that everyday planning question.
The useful connection is the handoff. Another caregiver can know where the clean supplies are, which feeding instructions to follow and when to call for help. A familiar evening sequence can stay flexible around illness. It should never become a reason to delay a hungry baby’s feed, extend gaps against medical advice or start night weaning while you are trying to recover.
Can I breastfeed while taking antibiotics or pain medicine?
Many medicines used during breastfeeding are compatible with it, including most antibiotics, but the exact medicine and your baby’s circumstances matter. Tell the prescriber and pharmacist that you are breastfeeding. Mention if your baby was premature, had jaundice or has other medical needs.
The NHS breastfeeding and medicines guide discusses paracetamol, called acetaminophen in the United States, and ibuprofen. Check what is appropriate for you, follow the package or prescribed directions, and avoid accidentally doubling an ingredient in combination products. This article is not a dosing schedule.
Do not use leftover antibiotics or someone else’s prescription. Not every inflamed breast needs the same treatment, and a medicine that helped a friend may be wrong for you. If an antibiotic is prescribed, take it as directed and contact the prescriber about side effects or lack of improvement.
Ask whether there are any baby symptoms to watch for with your particular medicine. If your baby becomes unwell, feeds poorly or develops a concerning reaction, get medical advice rather than assuming it is harmless because it happened during your treatment.
I would write down the medicine name, the instructions and the number to call with a problem. Keep medicines in their original packaging and out of children’s reach. When another adult is helping, a clear note is more useful than both of you trying to remember the last dose.
What changes if there is an abscess, open wound or MRSA?
A painful lump or swelling with a warm, sore breast needs assessment. An abscess is a collection of pus; it may need ultrasound and drainage as well as other treatment. The NHS breast abscess guide explains that breastfeeding can often continue during treatment. Do not try to squeeze or drain a suspected abscess yourself.
With an open infected area, feeding safety depends on contact. The CDC’s MRSA guidance says most healthy babies can continue receiving breast milk, but their mouth must not touch pus, open infected tissue or a drain site. A pump flange also needs to avoid infected tissue and the drain insertion area.
Ask the treating team how to cover the wound and position feeding or pumping equipment. If contact cannot be avoided, they may advise temporarily expressing and discarding milk from that side while treating the infection. Get explicit advice about when to resume; do not choose a waiting period yourself.
Premature babies, babies in a neonatal unit and other medically vulnerable babies may need different precautions. Tell their team about the breast infection before applying the usual advice for a healthy term baby. Keep any milk-handling instructions with the expressed milk so the next caregiver does not have to guess.
Ask for a specific feeding plan when…
There is an open infected wound or drainage near the nipple or pump flange.
A drain or dressing changes where your baby can safely latch.
Your baby is premature, in a neonatal unit or has medical vulnerabilities.
Swelling, pain or refusal means your baby is not getting a workable feed.
The plan should cover both your treatment and what your baby will receive at the next feed.
Watch your baby’s intake, not just the pump bottle
While you are sore and distracted, it is easy to focus entirely on the affected breast. Keep noticing your baby too: are they waking for feeds, swallowing, having their usual wet diapers and behaving as expected? The NHS guide to getting enough milk uses feeding observations, diaper output and weight together.
One small pumping session does not measure everything your baby received directly at the breast. Equally, a baby staying attached for a long time does not settle whether milk transfer is effective. If you are unsure, ask someone skilled in breastfeeding to observe a feed and help assess intake.
Seek prompt advice for poor feeding or fewer wet diapers than usual. A baby who is difficult to wake, has breathing difficulty or turns blue or grey needs emergency help. A young baby’s fever also needs urgent medical assessment. Do not assume a baby who seems ill is simply reacting to your mastitis or medicine.
If extra milk is needed, ask what to use, how to give it and how your own milk-removal plan should adapt. A feeding plan should be workable for the baby and for an unwell parent, with follow-up rather than a vague instruction to “try harder.”
Milk handling and pump care during mastitis
Ordinary mastitis does not automatically make previously expressed milk unusable. Follow normal safe milk-storage guidance, and check with your clinician when a wound, contamination concern or particular treatment changes the advice. Label any milk that has special instructions so it is not mixed into the usual feeding supply by mistake.
Wash your hands before handling milk or pump equipment. Clean the parts that touch milk after use, let them dry fully and follow the manufacturer’s directions. The CDC pump-cleaning guide explains additional sanitizing, particularly for babies under two months, those born prematurely or those with weakened immune systems.
You do not need to turn illness into a whole-house disinfection project. Ask a helper to take over the actual equipment-cleaning steps if you pump. That is more useful than repeatedly scrubbing already-clean furniture while the feeding kit is waiting in the sink.
Give the next caregiver a plan they can use
When you feel feverish, repeating the same explanation to every person in the house is tiring. Put the practical information in one place: the current feeding plan, any clinician instructions, the medicine schedule and who will call for help if symptoms change.
Four jobs another adult can take
Bring: water, food, a clean cool cloth and the phone.
Handle: diaper changes, settling and safe pump-equipment cleaning.
Remember: the agreed feeding and medicine instructions, without improvising extra pumping.
Act: help arrange care if you worsen or your baby is not feeding well.
“Rest more” becomes useful when it comes with an actual handoff. A friend might bring a meal; a partner might manage the laundry and calls. If you are alone, ask your maternity service or clinician what support is available and tell them if being unwell is making baby care difficult.
If you feel too drowsy or unwell to hold your baby safely, place them in their safe sleep space and get help. Do not settle in a sofa or armchair with the baby when you may fall asleep. Needing another adult to take over is a practical care decision.
What if mastitis keeps coming back?
Recurring symptoms deserve a fresh assessment. Bring the earlier treatment details and explain whether it is the same area each time. A persistent lump, a change that does not resolve or repeated episodes should not be treated indefinitely as the same familiar problem without examination.
Ask for help reviewing the whole feeding pattern: attachment, painful pumping, sudden changes in milk removal and any extra sessions added to build a freezer supply. Avoid changing several things at once on your own. It is easier to judge a plan when you know what was changed and why.
If you want to reduce or stop breastfeeding, say so. You can ask for a gradual plan that fits your wishes and protects comfort while your baby receives appropriate feeds. Abruptly stopping because you fear the milk is automatically unsafe is a different decision from choosing a supported transition.
An optional reusable cold pack
A clean cloth soaked in cool water is an already-owned option for comfort. If you prefer a reusable pack, Lansinoh TheraPearl 3-in-1 Breast Therapy Packs, two-pack with soft covers are one product to compare. The manufacturer describes hot and cold uses; the relevant option here is gentle cooling, not adding heat or pumping to treat mastitis.
Use the supplied cover, follow the instructions for your exact pack and your clinician’s advice, and stop if your skin becomes uncomfortable. The manufacturer limits a session to no more than twenty minutes; shorter use may suit you. Do not fall asleep with a pack, use it on an open wound or let it replace medical assessment. You do not need to buy a product to continue breastfeeding or seek care.

Watch: a gentle hand-expression technique
This UNICEF UK Baby Friendly Initiative video, also embedded by Guy’s and St Thomas’ NHS, demonstrates hand expression. It is a general technique resource, not a mastitis treatment plan. Follow your clinician’s advice about whether, when and how much to express; do not use it as a reason to massage deeply or keep trying to empty a swollen breast.
Written takeaway: wash your hands, use a suitable clean container and gently compress and release with your finger and thumb behind the nipple rather than dragging across the skin. Stop a painful attempt and ask for help. The NHS written technique guide is available if the video does not load; its general milk-expression advice still needs to fit your individual mastitis plan.
Common questions about feeding with mastitis
Should I always start on the affected side?
No universal rule fits every sore breast. Comfort, swelling and milk transfer matter. Avoid repeatedly targeting one side to clear it. Ask for a plan if the affected side is difficult to use or your baby is not getting enough.
Do I need to pump and dump?
Not routinely for mastitis alone. An infected wound that contaminates milk, a particular medicine or a vulnerable baby’s care plan can change the answer. Ask which milk is affected and what condition must be met before using it again.
Does needing antibiotics mean breastfeeding failed?
No. Treatment addresses a health problem. You can tell the clinician that continuing breastfeeding matters to you and ask how to make that workable. You can also ask for help if you want to change your feeding plan.
Can I wait until morning?
That depends on how you and your baby are doing, not just the clock. Emergency symptoms need immediate help, worsening illness needs prompt advice, and a baby who is not feeding needs a plan now. Use your local out-of-hours service when your usual clinic is closed.
Will changing my baby’s sleep schedule fix this?
No sleep schedule treats mastitis. Do not delay needed feeds, add pumping sessions or start night weaning as a home treatment. Discuss feeding changes with the clinician or lactation professional helping you recover.
Keep feeding possible while getting the care you need
The usual answer is that breastfeeding can continue. The useful next step is making that possible without forcing painful milk removal or ignoring worsening symptoms. Ask for a plan that covers your breast, your baby’s next feed and the help you need between them.

Thank you so much for this video! I had no idea about the dangers of baby swings :O
Hi Mary-Ann. I have a question: Is method in any way similar to the ones recommended by Dr Bucknam, Dr. Weissbluth or Dr. Karp? We tried those but none of them help.
Hi Regina, thank you for your question. The short answer is no. The techniques I share in my guide are based on newest scientific research and this is why I have never seen any approach similar to the one I recommend.
This method really works! I tried it on my son Jesus and after just one week he went from waking up more than 5 times a night to waking up just once or twice. You are a lifesaver, Mary-Ann!
I'm truly impressed with how much information you share in your video. And all for free! I can feel that you truly care about mothers like myself, and that's hard to find these days. I have recommended your site to several of my friends already.
Mary-Ann, our child suffers from autism. Is your approach still suited?
Chloe, I made sure my method can be used with any child, even babies who are special like yours. Please note that I'm not a doctor and that I always advice to consult with your physician because nothing is more important than the safety and well-being of your love.
Hallo Mary-Ann, I'm from Germany. Do you have your guide in German?
Hello Heide, we do! Normally you should already see our video in German. If not, please contact our support so they can guide you
Thenk you for your answer, Mary-Ann!
I just completed your approach and I have to say, it worked almost too well. Yes, it took a bit of getting used to with your bedtime routine but the difference is huge. My son George used to take 1 hours to go down and now he's firmly asleep in no more than 10 minutes! You're the best!
It seems I'm the only man watching this video, lol! What you shared about the 'emotional backpack' made immediate sense to me and I can't wait to help my little girl Mila to unpack it!
Hey there, just discovered your site and this really sounds different. Just wanted to say thanks for sharing :)
For everyone who's still thinking about getting Mary-Ann's guide I want to advise you to go ahead. I wasn't sure myself but now I'm so thankful I invested in this program. It made a huge difference in our life as a family and yes, my baby girl does sleep through the night now.
