Sore nipples during breastfeeding are most often caused by a shallow latch, and fixing how your baby attaches to the breast is the single most effective way to get relief. Some tenderness in the first week is common as your skin adjusts, but pain that persists beyond those early days, gets worse over time, or causes visible damage like cracks or bleeding signals a problem worth solving. The good news: most causes are fixable, and several strategies can ease the pain while you work on the root issue.
What Normal Soreness Looks Like
Mild nipple sensitivity during the first week of breastfeeding is extremely common. Your skin is adjusting to a new, repetitive stimulus, and brief tenderness at the start of a feeding that fades as your baby settles into a rhythm is typical. This early soreness should steadily improve, not worsen.
Pain that persists through an entire feeding, continues between feedings, or shows up as cracking, blistering, bleeding, or misshapen nipples after your baby unlatches is not a normal part of the adjustment period. These are signs that something about the latch, your baby’s anatomy, or another underlying issue needs attention.
Fix the Latch First
A shallow latch is the most common reason for sore nipples. When your baby only takes the nipple into their mouth without enough of the surrounding breast tissue, the nipple gets compressed against the hard palate with every suck. A deep, asymmetric latch spreads that pressure across a wider area and dramatically reduces trauma.
To get there, support your baby’s back, neck, and the base of the head behind the ears rather than cupping the back of the skull. Position your baby so the chin touches your breast first and the nipple lines up with their upper lip. Wait for a wide-open mouth, then bring your baby to the breast. When latched correctly, you should see more of your areola visible above your baby’s top lip than below the bottom lip. The latch should feel like a deep tug, not a pinch.
If your nipple comes out of your baby’s mouth looking flattened, creased, or lipstick-shaped, the latch was too shallow. Break the seal gently with a finger and try again rather than powering through a painful feeding.
Try a Laid-Back Position
The position you nurse in can make a significant difference. In a laid-back (or “biological nurturing”) position, you recline at roughly a 15 to 65 degree angle with your baby lying tummy-down on your body. Gravity keeps your baby’s full body pressed against yours, which activates natural reflexes that help them find and latch onto the breast more deeply on their own.
A meta-analysis of studies on this position found it significantly reduced both nipple pain and nipple trauma compared to upright positions. It also led to better latch quality overall. If you’ve been sitting bolt upright or hunching over your baby, simply leaning back and letting your baby rest on you can take pressure off your nipples while your baby does more of the latching work instinctively.
Soothing Sore Nipples Between Feedings
While you work on improving the latch, several strategies can help manage the pain and support healing between feedings.
- Expressed breast milk: Rubbing a few drops of your own milk onto the nipple after a feeding and letting it air dry provides natural moisture and mild antimicrobial protection.
- Purified lanolin: A thin layer keeps damaged skin moist and supports healing. It doesn’t need to be wiped off before the next feeding.
- Silver nursing cups: Small caps made of silver that sit over the nipple between feedings. In one clinical trial, 69% of women using silver cups experienced complete pain resolution within seven days compared to 21% using standard care. Bleeding resolved in 94% of the silver cup group in that same timeframe, with no adverse reactions reported.
- Hydrogel pads: These cooling pads can ease surface pain and prevent the nipple from sticking to your bra or nursing pad.
Avoid letting nipples stay damp against fabric, which softens skin and makes it more vulnerable to further damage. Changing nursing pads frequently helps.
When Vasospasm Is the Problem
If your nipple turns white or blanches after your baby unlatches, followed by a color shift to blue or purple and then red before returning to normal, you’re likely experiencing vasospasm. This happens when blood vessels in the nipple constrict suddenly, often triggered by cold air hitting a wet nipple or by compression from a shallow latch. The pain can be intense, often described as burning or throbbing, and it hits after the feeding rather than during it.
Warmth is the most effective immediate relief. Press a warm cloth or heating pad against your nipple right after unlatching. Wear an extra layer over your chest, and avoid exposing your nipples to cold air. Warming the bathroom before you undress for a shower helps prevent flare-ups. Contrary to older advice about “airing out” sore nipples, keeping them warm and covered is better when vasospasm is involved.
Check for Tongue Tie
A tongue tie (ankyloglossia) restricts the range of motion of a baby’s tongue, making it harder for them to latch deeply and maintain a good seal. It affects roughly 4 to 16% of newborns and can cause persistent nipple pain and trauma even when positioning and latch technique look right from the outside.
Signs that a tongue tie might be contributing include nipple pain that doesn’t improve despite latch corrections, a clicking sound during feeding, your baby frequently slipping off the breast, and nipples that consistently come out compressed or misshapen. A lactation consultant can evaluate tongue function using standardized assessment tools. If a significant restriction is identified, a simple release procedure often leads to rapid improvement in both latch comfort and feeding efficiency.
Infections and Deeper Pain
Persistent burning, shooting, or stabbing pain in the nipple or deeper in the breast that doesn’t match the mechanical pattern of latch-related soreness can point to an infection. For years, this type of pain was commonly diagnosed as nipple thrush (a yeast infection), but recent clinical evidence has shifted that understanding significantly. According to researchers at Cleveland Clinic, there is now little to no evidence that yeast infections actually occur on the nipple, and many parents were likely misdiagnosed.
What was previously called thrush is now more often understood as part of the mastitis spectrum. This spectrum starts with mammary dysbiosis (a disruption in the normal bacterial balance of the breast), which can progress to inflammatory mastitis, bacterial mastitis, and in severe cases, abscess. The symptoms can overlap with what was once attributed to yeast: redness, cracked skin, swelling, and deep pain.
If your pain is worsening, doesn’t respond to latch improvements, or is accompanied by redness, warmth, or fever, getting an accurate diagnosis matters because the treatment approach differs from what would be prescribed for a yeast infection.
Practical Tips That Add Up
Small adjustments throughout your day can reduce cumulative nipple stress. Start feedings on the less sore side first, since babies suck most vigorously at the beginning when they’re hungriest. If both sides are equally painful, hand express or pump briefly before latching to trigger your let-down reflex so your baby doesn’t have to suck as hard to get milk flowing.
Break the suction before removing your baby from the breast by sliding a clean finger into the corner of their mouth. Pulling a baby off without breaking the seal can cause or worsen cracks. If pain is severe enough that you need a break, pumping on the affected side for a feeding or two gives your skin time to heal without disrupting your supply. Use the lowest comfortable pump suction setting and make sure your flange size is correct, since a too-small flange creates the same compression problem as a shallow latch.
Nipple soreness that improves steadily over the first week or two and responds to latch adjustments is typically on its way to resolving completely. Pain that plateaus, worsens, or comes with visible skin changes after the first two weeks is worth bringing to a lactation consultant, who can watch a full feeding and assess both your technique and your baby’s oral anatomy in real time.
