Nipple soreness during breastfeeding is one of the most common postpartum complaints, affecting roughly 76–79% of women in the first days after birth. The good news: most soreness is caused by fixable issues like a shallow latch, and several effective remedies can speed healing while you continue nursing. Here’s what actually helps and when soreness signals something that needs professional attention.
Why Breastfeeding Makes Nipples Sore
The single most common cause is a shallow latch. When your baby latches onto only the nipple instead of taking a deep mouthful of the areola, all the suction pressure concentrates on a small, sensitive area. Signs of a shallow latch include seeing most of your areola while your baby feeds, their mouth barely open, their chin not touching your breast, and pain that starts the moment they latch on.
Other causes include tongue-tie or a cleft lip in the baby (both of which restrict how well they can use their mouth), pump flanges that are the wrong size or set too high, and skin conditions like eczema on the nipple. Sometimes the cause is a yeast infection (thrush) or a bacterial infection that develops in cracked skin. Each of these requires a slightly different approach, so figuring out the underlying cause is the fastest path to relief.
Fix the Latch First
No amount of nipple cream will solve soreness if the latch stays shallow. To get a deeper latch, wait until your baby opens wide, then bring them quickly to the breast so they take in a large portion of the areola, not just the nipple tip. Their lips should flare outward, and you should hear steady swallowing rather than clicking sounds.
A laid-back or “biological nurturing” position can make a noticeable difference. You recline at roughly a 45-degree angle with your baby lying stomach-down on your chest. In this position, your baby’s natural reflexes (rooting, stepping, crawling movements) help them find and latch onto the breast more deeply on their own. A meta-analysis found that this position significantly improved correct latching and reduced nipple trauma compared to upright feeding positions. It also gives your baby full-body contact for stability, which means less sliding and less friction on the nipple.
If adjusting positions and latch technique doesn’t reduce pain within a few feeds, a lactation consultant can watch a full feeding session and spot problems you might not notice yourself, including whether your baby has a tongue-tie that limits their latch depth.
Topical Remedies That Help Healing
Once the latch is addressed, your nipples need a chance to heal. The most widely recommended approach is moist wound healing: keeping the damaged skin from drying out and cracking further. Purified lanolin applied after each feeding creates a moisture barrier without needing to be wiped off before the next feed. Expressing a few drops of breast milk and letting it dry on the nipple also provides a natural protective layer with mild antimicrobial properties.
Silver nursing cups are a newer option with promising evidence behind them. These small caps fit over the nipple between feedings and use the antimicrobial properties of silver to protect damaged skin. In a randomized trial of women with moderate to severe nipple fissures, 69% of those using silver caps had complete pain resolution within seven days, compared to 21% receiving standard care. Bleeding resolved in 94% of the silver cap group in the same timeframe, with no significant side effects reported.
Hydrogel pads are another option that can soothe cracked nipples with a cooling effect. However, they do carry some risk if used incorrectly. FDA adverse event reports have flagged two issues: allergic reactions in people sensitive to glycerin (a key ingredient in most hydrogel pads) and bacterial contamination when pads are left exposed and then placed back on broken skin. If you use them, store them in a clean, sealed container between uses and replace them according to the manufacturer’s instructions.
Breast Pump Soreness
If your pain is worse during pumping than during direct breastfeeding, the pump itself may be the problem. The most common culprits are a flange that doesn’t fit your nipple (too small causes friction, too large pulls in extra areola tissue) and suction set higher than necessary. Your nipple should move freely in the flange tunnel without rubbing the sides, and effective pumping doesn’t require maximum suction. Starting at a low setting and increasing only until milk flows well protects the skin while still emptying the breast.
Vasospasm: When Pain Comes After Feeding
Some people notice intense, burning pain after the baby unlatches, often accompanied by the nipple turning white, then blue or purple, before returning to its normal color. This is nipple vasospasm, a condition where blood vessels in the nipple constrict suddenly, cutting off blood flow temporarily. It’s similar to Raynaud’s phenomenon in fingers and toes and can be triggered by cold air or sudden temperature changes.
Warmth is the most effective immediate treatment. Applying a warm compress right after feeding, wearing an extra layer over your chest, and warming the bathroom before undressing for showers all help prevent episodes. Avoid “airing out” your nipples, which is sometimes suggested for general soreness but actually worsens vasospasm by exposing the nipple to cool air.
Signs of Infection
Cracked nipples create an entry point for bacteria and yeast, so it’s important to recognize when soreness has crossed into infection territory.
Thrush (a yeast infection) typically causes shooting or burning pain that continues between feedings, along with redness, cracked skin, or swelling around the nipple. Your baby may also have white patches inside their mouth. Thrush doesn’t resolve on its own and needs antifungal treatment.
Bacterial infections of the nipple skin can develop when cracks or fissures don’t heal. If redness spreads, you notice pus, or the pain intensifies rather than gradually improving, a topical antibiotic ointment is usually the first-line treatment.
Mastitis is the most serious escalation. Watch for a fever of 101°F (38.3°C) or higher, a wedge-shaped area of redness on the breast, breast swelling or warmth, a hard lump, or a general feeling of being unwell, similar to the flu. These symptoms need prompt medical attention because untreated mastitis can progress to an abscess.
What’s Normal and What’s Not
Some tenderness in the first week of breastfeeding is expected as your nipples adjust to frequent suction. This transitional sensitivity typically peaks around days three to five and then starts to ease. Pain that persists beyond the first two weeks, gets worse rather than better, or is severe enough to make you dread feeding is not a normal part of the adjustment period.
By eight weeks postpartum, about 20% of women still report nipple pain and 8% still have visible nipple trauma. If you’re in that group, the cause is almost always identifiable and treatable. A shallow latch, an undiagnosed tongue-tie, an undetected infection, or vasospasm can all keep the cycle of damage and incomplete healing going indefinitely. Getting a professional latch assessment is the single most effective step, because once the mechanical cause is corrected, most nipple injuries heal within days.
