Sore Nipples Breastfeeding: Causes, Relief & How to Heal Fast
By Teddyy Editorial Team | Last Updated: April 20, 2026
Sore nipples breastfeeding pain is one of the most common challenges new mothers face — and it is almost always fixable. While breastfeeding is a natural and deeply bonding experience, it should not be painful. If you are experiencing sore, cracked, or bleeding nipples, you are not alone: studies show that up to 80–90% of new mothers report nipple pain in the first weeks of nursing.
The good news is that in the vast majority of cases, the cause is identifiable and the solution is straightforward. This guide walks you through exactly why sore or cracked nipples happen during breastfeeding, what each type of pain means, and how to treat and heal them — so you and your baby can get back to comfortable, enjoyable feeds.
Why Are My Nipples Sore, Cracked, or Bleeding? (Causes Overview)
Before treating the symptom, it is important to identify the cause. Not all nipple pain during breastfeeding has the same origin, and treating the wrong cause will delay healing. The most common causes of sore nipples breastfeeding pain are:
- Poor latch — the single most frequent cause, responsible for the majority of nipple soreness and cracking in new mothers
- Nipple thrush (fungal infection) — causes a burning, shooting pain that differs from latch-related soreness
- Breast pump flange size — an incorrectly sized flange creates friction and compression that damages nipple tissue
- Engorgement or fast letdown — a very full breast can make it harder for baby to latch deeply, causing nipple compression
- Tongue-tie or lip-tie in the baby — restricts how far baby can take the breast into their mouth
- Dry skin or eczema — environmental or skin-condition causes that crack the nipple surface independently of feeding
Identifying which cause applies to you is the first step. Read through each section below to find the match.
Poor Latch: The #1 Cause of Sore and Cracked Nipples
A poor latch is by far the most common reason for sore nipples during breastfeeding. When your baby latches correctly, your nipple rests against the soft part of their palate (the soft palate) and is not compressed during sucking. When the latch is shallow, your nipple is instead compressed against the hard palate — which causes significant pain and, over time, cracking and bleeding.
Signs your baby has a poor latch:
- Your nipple looks flat, wedge-shaped, or has a white stripe at the tip after a feed (called “lipstick nipple”)
- You hear clicking sounds while the baby feeds
- Pain continues throughout the entire feed rather than easing after the first 30 seconds
- Your baby frequently slips off the breast mid-feed
- The baby is not gaining weight at the expected rate
How to correct the latch:
Position your baby so that their nose is level with your nipple before they open their mouth. Wait for a wide, gaping mouth — like a yawn — then bring your baby to the breast (not your breast to the baby). Aim your nipple toward the roof of their mouth. Their chin should press into the breast first, and you should see more of the areola below the mouth than above it. Their lips should flare outward like a fish, not tucked in.
If your nipple appears distorted after feeds, or pain is not improving after the first two weeks, ask your midwife, health visitor, or a certified lactation consultant (IBCLC) to observe a full feed and assess the latch. This single intervention resolves the majority of breastfeeding pain.
Other Causes: Thrush, Pump Fit, Engorgement, and Skin Conditions
Nipple Thrush (Fungal Infection)
Nipple thrush is caused by an overgrowth of Candida albicans — the same organism that causes oral thrush in babies and vaginal thrush. It often develops after a course of antibiotics. Unlike latch pain, thrush pain has a distinct profile: a deep, burning, or shooting sensation that may radiate into the breast, persisting between feeds rather than only during them. The nipple and areola may appear pink, shiny, or slightly flaky.
If you suspect thrush, see your doctor. Both you and your baby need to be treated simultaneously (even if the baby shows no symptoms) to prevent reinfection. Antifungal creams applied to the nipple after each feed, combined with oral antifungal drops for the baby, are the standard treatment. Untreated thrush does not resolve on its own.
Breast Pump Flange Fit
If you regularly use a breast pump and are experiencing nipple soreness specifically after pumping sessions, check your flange (the funnel-shaped cup) size. The tunnel of the flange should allow your nipple to move freely without rubbing on the sides — there should be roughly 1–3mm of space around the nipple. If the fit is too tight, the friction causes abrasion and swelling. If too loose, excessive suction is applied to the areola.
Most pumps come with 24mm flanges by default, but nipple sizes vary widely. Many women find they need a smaller size (17–21mm). Consult the pump brand’s sizing guide or a lactation consultant for help measuring.
Breast Engorgement
When breasts are very full and firm, the areola becomes tight and difficult for the baby to grasp deeply. This pushes the latch forward onto the nipple alone. Before a feed, if you are engorged, use gentle reverse pressure softening — press your fingertips gently around the base of the nipple for 60 seconds — to move fluid away from the areola and allow the baby to latch more deeply.
Tongue-Tie or Lip-Tie
A tongue-tie (ankyloglossia) restricts the baby’s tongue movement, preventing them from extending the tongue over the lower gum to cushion the nipple during sucking. The result is a characteristic striped or compressed nipple appearance after feeds, combined with pain. A paediatrician or lactation consultant can assess your baby for tongue-tie and refer you for a frenotomy (division of the tie) if appropriate.
How to Manage Sore Nipples During Breastfeeding
Once you have identified the likely cause of sore nipples breastfeeding pain, these at-home measures help manage discomfort and support healing during feeds:
- Let breastmilk air-dry on the nipple — after each feed, express a few drops of hindmilk and rub gently over the nipple, then allow to air-dry. Breastmilk contains antibacterial and healing properties.
- Apply 100% pure lanolin cream — medical-grade lanolin (such as Lansinoh or Medela Purelan) creates a moist healing environment on cracked skin without needing to be wiped off before feeds. Apply a thin layer after each feed.
- Alternatively, use coconut oil or silverette cups — virgin coconut oil has mild antifungal and moisturising properties; silverette nursing cups (made from 925 silver) create an antimicrobial microenvironment between feeds and are preferred by some mothers who find creams messy.
- Do not shorten feeds — shorter feeds do not reduce nipple pain and may compromise your milk supply. Address the root cause, not the feed duration.
- Start feeds on the less painful side — your baby sucks most vigorously at the start of a feed when hunger is strongest. Beginning on the less affected nipple means that by the time they switch sides, the sucking intensity has reduced.
- Use a warm compress before feeding — a warm flannel applied to the breast for a minute before latching encourages milk flow and softens the areola, making it easier for baby to latch deeply.
- Take pain relief if needed — paracetamol (acetaminophen) or ibuprofen are both compatible with breastfeeding and can make feeds more manageable while the cause is being addressed. Always follow your doctor’s guidance.
How to Treat Cracked or Bleeding Nipples
Cracked or bleeding nipples are a progression of sore nipples breastfeeding causes, and require the same root-cause approach, but deserve specific additional steps:
- Check and correct the latch first — every single feed. A cracked nipple will not heal if the cause continues.
- Hand express before latching — express 2–3 minutes before putting baby to the breast to trigger letdown. When milk is already flowing, your baby does not need to suck as hard to get milk, reducing compression force on damaged tissue.
- Apply cool gel pads or chilled cabbage leaves between feeds to numb pain and reduce inflammation.
- Use a hydrogel dressing — sterile hydrogel pads (available at pharmacies) applied between feeds maintain a moist wound-healing environment, reduce pain, and speed recovery significantly compared to air-drying alone for actively bleeding cracks.
- Leave prescribed ointments on overnight — if your doctor has prescribed a nipple ointment (such as a multi-ingredient APNO — all-purpose nipple ointment), nighttime application during the longest gap between feeds allows maximum absorption.
- Nurse on the less affected side last — or hand-pump that side and bottle-feed expressed milk temporarily to allow a deep crack to begin closing.
- Unlatch gently — insert a clean finger into the corner of baby’s mouth to break the suction seal before removing them from the breast. Never pull baby off while actively sucking.
Is it safe to breastfeed with bleeding nipples?
Yes, in the vast majority of cases. Small amounts of blood in the milk will not harm your baby, though they may spit up pink-tinged milk, which can be alarming but is harmless. If you are HIV-positive or have a blood-borne condition, consult your doctor before continuing to feed through active bleeding.
When to See a Doctor or Lactation Consultant
Seek professional support promptly if:
- Pain is severe and not improving after correcting the latch over 2–3 days
- You develop a fever, flu-like symptoms, or a hard, red, hot area on the breast — these are signs of mastitis, a breast infection that requires antibiotics
- Nipple pain has a burning, shooting quality between feeds (possible thrush)
- Your baby is not regaining birth weight or gaining weight adequately
- A crack has not begun to heal within 5–7 days despite correct latch and treatment
A certified lactation consultant (IBCLC) is the most qualified professional to observe a full breastfeeding session and identify the exact cause of your sore nipples breastfeeding pain. Many hospitals, community health centres, and breastfeeding support groups (such as La Leche League India) offer lactation support — often at low or no cost.
You Don’t Have to Manage Breastfeeding Pain Alone
Nipple pain is the number one reason mothers stop breastfeeding earlier than they intended. But with the right support, most causes are completely resolvable.

Frequently Asked Questions
How long do sore nipples last when breastfeeding
Initial nipple tenderness in the first 1–2 weeks is normal as your skin adapts to breastfeeding. If the latch is correct, this tenderness typically resolves by weeks 2–4. Pain that persists or worsens beyond two weeks signals a specific cause that needs addressing.
How long do cracked nipples take to heal
With the correct latch, appropriate moisture (lanolin or hydrogel dressing), and no ongoing trauma, a shallow crack typically heals within 3–7 days. Deeper cracks may take 1–2 weeks. Healing will not progress if the root cause — usually a shallow latch — has not been corrected.
Should I stop breastfeeding if my nipples are cracked and bleeding
In most cases, no. Stopping or skipping feeds leads to engorgement and can affect milk supply. Instead, temporarily use a hospital-grade electric pump on the affected side to maintain supply while the nipple heals, and feed from the unaffected breast. Resume feeding on both sides as soon as the crack begins to close.
Does nipple cream need to be washed off before breastfeeding
Medical-grade lanolin (100% purified) does not need to be washed off before feeding — it is safe for your baby to ingest in the small quantities applied. Most hydrogel pads and coconut oil are also safe. Always check the label of any cream you use to confirm it is breastfeeding-safe.
What is the difference between nipple soreness and nipple thrush
Latch-related soreness is worst at the beginning of a feed and in the first few seconds of attachment, easing as the feed progresses. Thrush pain is a deep, burning, or shooting sensation that often worsens after feeds and continues between them. Thrush also tends to be bilateral (both breasts) and is often accompanied by symptoms in the baby’s mouth (white patches that don’t wipe off).
Can I use nipple shields for sore nipples
Nipple shields (thin silicone covers worn over the nipple during feeding) can provide temporary relief for very sore or damaged nipples. However, they should only be used under the guidance of a lactation consultant, as incorrect use can reduce milk transfer, affect supply, and become difficult to wean the baby from. They are a tool, not a first-line solution.
Does wearing a bra affect nipple healing
A well-fitting, non-underwired nursing bra that allows air circulation supports healing. Avoid synthetic fabrics that retain moisture. Some mothers find going bra-free at home, or using breast shells (hollow domes that prevent fabric touching the nipple) helpful during the healing phase.
