Mastitis when breastfeeding twins or triplets: symptoms and support

Understanding mastitis when feeding more than one baby

Mastitis is inflammation in the breast that can cause a hot, swollen and painful area. It’s most common during breastfeeding and sometimes involves an infection.

When you’re feeding twins, triplets or more, feeling unwell can make an already demanding day much harder. Getting practical help and early feeding support can make a difference.

Mastitis doesn’t mean you’ve done anything wrong. It can happen even when feeding has been going well. You can usually continue breastfeeding while you recover but if you’re concerned speak to your GP.

Recognising mastitis and reducing your risk

Symptoms often develop quickly and usually affect one breast. You might notice:

• a hot, swollen or tender area
• a hard patch or wedge-shaped lump
• burning pain during feeds or between them
• changes in skin colour, although redness may be harder to see on brown or black skin
• aches, chills, tiredness or a high temperature

You don’t need to have every symptom to ask for help.

Keeping feeding comfortable

Feed in response to your babies’ hunger cues, such as turning towards the breast or bringing their hands to their mouths. Try not to delay feeds deliberately.

If your breasts feel uncomfortably full between feeds, hand express a small amount for comfort. Expressing more than you need can increase milk production and make fullness worse.

Ask your midwife, health visitor or breastfeeding supporter to check each baby’s positioning and attachment if feeding is painful or difficult. One baby may need different support from the other.

Planning for time away

If you’ll be apart from your babies, plan how you’ll express around their usual feeds. Avoid adding extra pumping sessions simply to keep your breasts empty.

Choose a comfortable bra that supports your breasts without pressing tightly against them. If you’re changing your feeding routine or reducing breastfeeds, seek advice about making changes gradually. Overproduction and sudden changes in milk removal can contribute to inflammation.

Managing busy days and celebrations

Trips, visitors and family gatherings can interrupt your usual routine. Let others know when you need time to feed or express, and ask them to take over practical tasks.

You don’t need to fit feeding around everyone else’s plans. Having someone organise meals, shopping or visitors can give you more space to respond to your babies.

Easing mastitis symptoms at home

Continue breastfeeding according to your babies’ needs. If feeding from the affected breast is too painful, hand express enough milk to meet their usual needs.

If you normally pump, keep to your usual routine rather than adding sessions or increasing suction to clear a painful area. Repeatedly trying to empty the breast can worsen inflammation. Avoid deep massage or forcefully pressing on a lump.

Apply a cold compress, such as a clean cloth soaked in cold water, for 10 minutes every hour to ease discomfort. Wear a comfortable, supportive bra if that feels helpful.

Paracetamol or ibuprofen can help with pain and are generally compatible with breastfeeding. Follow the packet instructions and ask a pharmacist if you’re unsure whether either medicine is suitable for you.

Avoid prolonged heat, which can increase inflammation. Rest when you can, keep drinks and easy meals nearby, and ask someone to help with the babies or household tasks.

When to seek medical help and feeding support

Contact your GP if symptoms haven’t improved within 12 to 24 hours of home care. Seek help sooner if you feel worse at any point. If your GP is closed, contact your local urgent medical advice service.

You may need antibiotics. If you haven’t improved after 48 hours of taking them, contact your GP again. Mastitis symptoms when you’re not breastfeeding also need medical assessment.

Twins Trust offers one-to-one feeding support from trained, NCT-accredited volunteers by email or phone. Visit our feeding support page to find out more. This service doesn’t replace medical assessment for mastitis.

For feeding advice, call the NCT Infant Feeding Line on 0300 330 0700, open 8am to midnight every day, including bank holidays. Don’t wait for a feeding support response if you need medical help.
