Breastfeeding Pain: Common Causes and How to Find Relief

Pain during breastfeeding is one of the most common reasons parents stop nursing earlier than they intended. That's understandable — feeding your baby shouldn't feel like something you have to endure. The reassuring reality is that most causes of breastfeeding pain are fixable, especially when addressed early. Knowing what to look for makes it much easier to find the right solution quickly.

What's Normal — and What Isn't

Some tenderness when your baby first latches in the early days is common. Your nipples are adjusting to a new kind of stimulation, and sensitivity often peaks around days two to five before gradually easing. This is normal.

What's not normal:

• Pain that lasts throughout the entire feed, not just at the moment of latch
• Cracked, blistered, or bleeding nipples
• Pain that gets worse over time rather than better
• Sharp or burning pain that persists between feeds
• Nipples that come out pinched, wedge-shaped, or like the tip of a lipstick after a feed

If you're experiencing any of these, something specific is usually going on — and it's worth investigating, not pushing through.

The Most Common Cause: A Shallow Latch

By far the most frequent cause of breastfeeding pain is a shallow latch. When a baby doesn't take in enough breast tissue, the nipple is compressed against the hard palate with every suck — causing friction, soreness, and sometimes lasting damage.

Signs of a shallow latch:

• Nipple comes out pinched, flattened, or lipstick-shaped after a feed
• Clicking or smacking sounds during nursing
• Baby's lips are tucked inward rather than flanged outward
• Baby's chin is not pressed into the breast
• Pain lasts throughout the feed, not just at the initial moment of latch

Signs of a deep, effective latch:

• Baby's chin is firmly against the breast, and nose is free and clear
• Lips are flanged outward like a fish
• More of the areola is visible above the top lip than below the lower lip
• You can hear rhythmic swallowing — suck, swallow, breathe
• Any tenderness at latch-on eases within the first few seconds

Even small adjustments to position can make a significant difference. A lactation consultant or breastfeeding counsellor who can watch a full feed in person is one of the most effective resources at this stage — many breastfeeding problems that feel unsolvable resolve quickly with hands-on help.

Other Common Causes

Engorgement

In the first days after your milk comes in, breasts can become very full and firm. A tightly engorged areola can flatten the nipple, making a deep latch harder to achieve. Hand expressing a small amount before feeding — just enough to soften the areola — usually helps the baby latch more deeply and comfortably. See Engorgement for a full guide to causes, relief techniques, and prevention.

Tongue-Tie (Ankyloglossia)

If a baby has a restricted frenulum — the small band of tissue under the tongue — they may not be able to extend their tongue far enough to latch deeply or cup the breast effectively. Tongue-tie can cause persistent pain that improves little with positioning adjustments alone.

Signs that tongue-tie may be a factor:

• Pain persists despite consistent latch corrections
• The baby makes a clicking sound and seems to lose suction during feeds
• The nipple is repeatedly compressed or striped after feeds
• The baby tires quickly at the breast, gains weight slowly, or is difficult to settle after feeds

A lactation consultant, midwife, paediatrician, or oral function specialist can assess for tongue-tie. If a frenotomy (tongue-tie release) is recommended, many families notice an improvement in feeding comfort quite quickly afterwards.

Thrush (Nipple Candidiasis)

A yeast overgrowth on the nipple or in the baby's mouth can cause burning, stinging, or shooting pain that often begins or persists between feeds — not only at latch-on. Thrush can develop after antibiotic use or alongside nappy rash and oral thrush in the baby.

Signs in the nursing parent:

• Deep, burning, or shooting pain that persists between feeds
• Nipples that look pink, shiny, flaky, or are unusually itchy
• Pain that doesn't improve with latch corrections

Signs in the baby:

• White patches on the tongue, cheeks, or gums that don't wipe away easily
• Persistent nappy rash not responding to usual treatment

Both parent and baby usually need treatment at the same time, even if only one shows clear symptoms — otherwise the infection can pass back and forth. Contact your healthcare provider for diagnosis: antifungal treatment is required and available on prescription.

Vasospasm (Raynaud's Phenomenon of the Nipple)

Some parents experience sharp, burning pain in the nipple after a feed, along with visible colour changes — the nipple turns white, then blue or purple, then red as blood flow returns. This is caused by blood vessels constricting in response to a temperature drop or shallow latch.

Helpful strategies:

• Apply warmth immediately after a feed — a warm compress, warm cloth, or cupping the breast with your hands
• Avoid moving from a warm environment to a cold one right after nursing
• Dress the chest area warmly between feeds
• A deeper, more effective latch reduces nipple trauma that can trigger vasospasm episodes

Vasospasm often responds to latch improvement alone. If it persists or significantly affects your wellbeing, speak with your healthcare provider — treatment options are available.

Mastitis and Blocked Ducts

Pain that is localised to one area of the breast, with redness, heat, or a firm lump, may point to a blocked duct or the early stages of mastitis. Flu-like symptoms, a fever above 38.5 °C, or a rapidly worsening painful patch suggests mastitis and warrants prompt medical attention. See Mastitis for a full guide to symptoms, treatment, and prevention.

What Helps Most

Latch and positioning first. Most breastfeeding pain improves when the latch deepens. Experimenting with different feeding positions — laid-back nursing, cross-cradle, rugby (clutch) hold — can help the baby open wider and take in more breast tissue. See Nursing Positions for a guide to each hold.

Unlatch and relatch whenever needed. If the latch is shallow and painful, insert a clean finger into the corner of the baby's mouth to break the suction before the baby comes off. Relatch as many times as needed — interrupting a shallow feed early protects the nipple from further damage.

Express milk to soften before latching. If engorgement is making a deep latch difficult, hand expressing a little milk first can soften the areola enough for the baby to latch more deeply.

Allow breast milk to air-dry on the nipple. After a feed, expressing a few drops and letting them dry on the nipple may support healing. Breast milk has natural antibacterial properties and is often recommended for sore nipples.

Apply purified lanolin or a hydrogel pad. If nipples are cracked or raw, medical-grade (purified) lanolin ointment or hydrogel pads can ease discomfort and protect the skin between feeds. Both are considered safe for the baby — there is no need to wipe off lanolin before feeding.

Avoid harsh soaps and alcohol-based products. These strip the natural oils that protect nipple skin. Rinsing with clean warm water only is enough during bathing.

Pain relief between feeds. Paracetamol or ibuprofen can help manage pain in the short term — both are compatible with breastfeeding. Ibuprofen's anti-inflammatory action may be particularly helpful where swelling or inflammation is a factor. Check with a pharmacist or healthcare provider if you have any uncertainty.

When to Get Help

Don't wait too long if things aren't improving. Reach out to a lactation consultant, midwife, or breastfeeding counsellor if:

• Pain doesn't improve within a few days of adjusting latch and positioning
• Your nipples are cracked, bleeding, or showing signs of infection
• You notice white patches in your baby's mouth (possible thrush)
• You feel a painful lump or red area on your breast
• You suspect tongue-tie may be limiting your baby's latch
• Breastfeeding is making you dread feeds — this is a signal, not a personal failing

Early help almost always leads to a faster resolution. Many breastfeeding problems that feel overwhelming improve significantly after a single in-person session with a skilled lactation consultant.
