Quick answer: A lot of breastfeeding advice glosses over pain with ‘it shouldn’t hurt if you’re doing it right.’ This is unhelpfully simplistic.
A lot of breastfeeding advice glosses over pain with ‘it shouldn’t hurt if you’re doing it right.’ This is unhelpfully simplistic. Some discomfort in the first 2 weeks is normal as nipples adapt. Pain throughout feeds, cracked or bleeding nipples, shooting pain between feeds — these are not normal, not inevitable, and not things you should push through. They have causes, and those causes have solutions.
The Most Common Cause: Latch Problems
Approximately 80–90% of breastfeeding pain comes down to latch. A shallow latch — where the baby takes only the nipple rather than a large mouthful of breast — creates a shearing force that damages nipple tissue rapidly. What a poor latch feels like: pain throughout the entire feed (not just the first 30–60 seconds), a pinching or biting sensation, nipple that comes out lipstick-shaped, misshapen, or white at the tip after feeds. What a good latch feels like: possible initial discomfort as baby latches on, which should resolve within 30–60 seconds into a pressure sensation rather than pain. To check and improve latch: ensure baby’s mouth is open very wide before latching (like a yawn, not a polite smile), aim your nipple toward the roof of the baby’s mouth rather than the centre, wait for the wide gape before pulling baby in quickly (chin first, then top lip), and check that you can see more areola above the top lip than below the bottom. If latch adjustment isn’t working after a day or two of trying, contact an IBCLC (International Board Certified Lactation Consultant) — they can watch a feed and identify specific issues that text descriptions cannot capture.
Nipple Damage: Prevention and Healing
If nipples are already cracked, blistered, or bleeding: express a few drops of breast milk and rub onto the nipple after each feed (has antimicrobial properties and supports healing); apply lanolin cream (Lansinoh) or medical-grade coconut oil between feeds; use a hydrogel pad for significant damage — the moist wound environment accelerates healing; consider an all-purpose nipple ointment (APNO) prescribed by a GP or lactation consultant for severe cases. Keep nipples from drying out between feeds — dry cracked skin heals more slowly than moist wound tissue. Don’t use soaps, breast pads that contain perfume, or any product containing alcohol on damaged nipples. Recheck latch — any degree of healing will be undone by the next poor latch.
Tongue Tie: When It’s Holding You Back
Tongue tie (ankyloglossia) affects approximately 4–11% of babies and is a significant cause of breastfeeding pain that frequently goes undiagnosed. The restricted tongue movement prevents the baby from flanging their lips, creates a shallow latch, and causes the characteristic nipple damage described above. Signs that tongue tie may be involved: pain despite correct latch technique; your baby makes a clicking sound during feeds (air entering because of poor seal); baby slips off the breast frequently; slow weight gain; and nipples that are consistently damaged. Posterior tongue ties (where the tight frenulum is at the back of the tongue rather than obviously at the front) are particularly commonly missed. An IBCLC or feeding specialist can assess for tongue tie; in the UK, the Association of Tongue-Tie Practitioners lists accredited assessors. Division (frenotomy) is a quick procedure done without general anaesthesia in young babies and typically results in immediate improvement.
Mastitis: Recognising and Treating It Quickly
Mastitis is infection of the breast tissue, presenting as a red, hot, firm, wedge-shaped area of the breast alongside flu-like systemic symptoms: fever (typically 38.5°C+), chills, body aches, and extreme fatigue. It develops when a blocked duct becomes infected — usually from mastitis-causing bacteria entering through a nipple crack. Treatment: continue breastfeeding or pumping from the affected breast (stopping allows the infection to worsen); antibiotics from your GP (flucloxacillin is first-line in the UK, dicloxacillin in the US); ibuprofen for anti-inflammatory effect and pain; warm compress before feeds; gentle massage toward the nipple. Start antibiotics within 24 hours of symptom onset — the risk of developing a breast abscess (which requires surgical drainage) increases significantly with delayed treatment. Mastitis is not a reason to stop breastfeeding — continuing to empty the breast is part of treatment.
Vasospasm: The Often-Missed Cause of Shooting Pain
Vasospasm causes shooting, stabbing, or burning pain in the nipple and breast, often occurring between feeds, after feeds, or when cold. The nipple may turn white, then purple, then red as blood flow is interrupted and then returns (Raynaud’s phenomenon of the nipple). Vasospasm is frequently mistaken for thrush because both cause nipple pain between feeds. Key difference: vasospasm pain changes with temperature (worse in cold, better with warmth); thrush causes burning pain that’s typically present during and between feeds, often with a whitish appearance in baby’s mouth. Treatment: keep nipples warm (apply a warm compress immediately after removing baby from the breast, wear wool breast pads); avoid cold exposure; for significant cases, nifedipine (a calcium channel blocker) prescribed by your GP is highly effective.
Frequently Asked Questions
How long should initial breastfeeding pain last?
Initial nipple tenderness as nipples adapt to the mechanical process of feeding is normal and usually resolves within 7–14 days. Pain that persists beyond 2 weeks, is present throughout the entire feed (not just the first 30–60 seconds), or involves visible nipple damage is not normal and has a fixable cause. Pushing through unresolved pain rarely leads to spontaneous improvement — it leads to further damage and sometimes early weaning. Seek help sooner rather than later.
Could I have thrush?
Possible, but thrush is significantly over-diagnosed as a cause of breastfeeding pain — largely because it’s easier to test for than vasospasm, latch problems, or posterior tongue tie. Signs that make thrush more likely: shooting, burning nipple pain during and between feeds; nipples appear pink, shiny, or flaky; baby has white patches in their mouth that don’t wipe away; recent antibiotic use (you or baby). If you’ve treated for thrush without improvement, consider whether the diagnosis was correct and request assessment by an IBCLC.
When should I consider stopping breastfeeding?
This is your decision and no one else’s. If breastfeeding is causing you significant physical pain, emotional distress, or affecting your ability to function as a parent — these are valid reasons to reconsider. That said, most breastfeeding pain is fixable with the right support. Before deciding to stop, get an IBCLC assessment — many women find that addressing the underlying cause transforms their breastfeeding experience. But if you’ve tried the support, addressed the problems, and still find breastfeeding unsustainable: formula is a safe, loving choice, and your wellbeing matters.
