When Breastfeeding Is Not Working

Health information for learning and planning — not medical advice, and not a substitute for your own clinician.

Clinician reviewedLast reviewed Aug 19, 2026

If feeding hurts, if you are worried about supply, or if you have had enough, there are more options than carrying on exactly as you are or stopping altogether. Most early problems are latch or positioning and improve quickly with skilled help. Some are physical, some are practical, and some are about what you can sustain, which is a legitimate reason on its own. This page is health information, not a substitute for a feeding assessment by someone who can watch a feed.

First: get a feed watched

Almost every early feeding problem is assessed by someone watching a whole feed. That is the step that is worth chasing.

Ask your midwife, health visitor, an infant feeding specialist, a lactation consultant, or a peer support service. NICE's postnatal guidance expects feeding support to be offered as part of postnatal care.

Bring specifics: what hurts, when, what the nipple looks like afterwards, how long feeds take, and how the baby behaves.

Pain

Pain through the whole feed usually means the latch needs adjusting, and the nipple's shape after a feed is the tell. Flattened, creased or wedge-shaped means the baby is not taking in enough breast tissue.

Other causes exist and need looking at rather than guessing: damaged skin, thrush, vasospasm, or the baby's tongue movement. Deep shooting pain after feeds, or nipples that blanch white and then hurt, is worth describing exactly.

Do not push through cracked, bleeding nipples for weeks. That is not commitment, it is an untreated problem.

Worries about supply

Most people worried about supply have enough, and the reassuring measures are nappies, stool colour and weight gain rather than how full the breast feels or how much a pump gets. A pump is not a measure of supply.

Genuinely low supply happens too. It can follow difficult births, heavy blood loss, thyroid problems, some medicines, retained placenta, or breast surgery, and it deserves an assessment rather than more effort.

Things that generally increase supply are frequent effective feeding or expressing, and a latch that works. Supplements sold to boost supply have weak evidence, and some interact with medicines, so ask before buying.

Mastitis and blocked ducts

A part of the breast that feels lumpy, tender and warm may be a blocked area. Keep feeding on that side if you can, and get it looked at if it is not settling.

Mastitis usually means a red, hot, painful area with fever, aches and feeling like you have flu. It needs same-day advice, because it can worsen quickly.

Feeding or expressing usually continues, and stopping suddenly can make it worse. See postpartum warning signs for what needs urgent care.

Mixed feeding

Combination feeding — some breastmilk, some formula — is a real option, not a failure state. It keeps some of the benefits of feeding while making the load survivable.

Introducing formula can reduce supply over time, so if you want to protect supply, discuss timing and amounts with a feeding specialist first. ACOG supports informed choice about how you feed, including mixed feeding.

Ask about paced bottle feeding and about how to keep at least some feeds at the breast if that matters to you.

Deciding to stop

Stopping is a legitimate decision, and the reason does not have to be medical. Mental health, pain, work, medicines, exhaustion, or simply not wanting to continue are all reasons enough.

Do it gradually where you can. Dropping one feed every few days is usually more comfortable and reduces the chance of blocked ducts or mastitis. Sudden stopping can hurt and can cause engorgement.

Expect a mood dip. Some people feel low for a few days as feeding ends, and knowing it may happen makes it easier. If low mood persists, read your mood after birth.

Expect your cycle to change. Periods often return within weeks of reducing feeds — see when your periods come back.

Guilt, and who it belongs to

Being told breastfeeding is best and then left without help is a system failure, not a personal one. WHO recommends breastfeeding at a population level; it does not follow that any individual who stops has done something wrong.

A fed baby and a functioning parent is the goal. If you are grieving the feeding relationship you wanted, that is real, and it is worth saying to someone rather than carrying alone.

Read the first two weeks of breastfeeding if you are still deciding, since many problems there are fixable.

When to see a doctor

Contact your midwife, health visitor or doctor for pain through feeds, damaged nipples, a lump that is not settling, worries about your baby's weight or nappies, or before starting or stopping anything if you take regular medicines. Seek same-day advice for a red hot painful breast with fever or flu-like aches.

Seek urgent advice about your baby for floppiness, difficulty waking, fast or laboured breathing, fever, or refusing feeds.

Seek care now: Get urgent care for a high fever with a red, hot, painful breast and feeling very unwell, for a breast abscess or a spreading red area, or for any baby who is floppy, hard to wake, breathing with difficulty or refusing feeds. Femio cannot assess a breast or a baby.

Frequently asked questions

How do I know if my supply is actually low?

Nappies, stool colour and weight gain, assessed by a clinician. Pump output and how full the breast feels are not reliable measures.

Can I keep feeding with mastitis?

Usually yes, and continuing to drain the breast normally helps. Get same-day advice, because mastitis can worsen quickly.

Is combination feeding allowed?

Yes. It is a common and reasonable choice, and a feeding specialist can help you protect supply if that matters to you.

What is the least painful way to stop?

Gradually, dropping one feed every few days where possible, so the breasts adjust.

Will stopping bring my periods back?

Often, within weeks of feeds reducing. Cycles are usually irregular at first.
