Nipple pain during breastfeeding is almost always caused by how your baby latches onto the breast, and fixing the latch is the single most effective way to stop the pain. While the first week or two of breastfeeding can involve some tenderness as your body adjusts, sharp pain, cracking, or bleeding is not a normal part of the process. Here’s what actually works to relieve the pain and prevent it from coming back.
Fix the Latch First
A shallow latch is the most common reason breastfeeding hurts. When your baby only grabs the nipple itself, their tongue and jaw rub directly against it instead of compressing the breast tissue underneath. This creates friction, soreness, and eventually cracked or bleeding skin. A deep latch, by contrast, draws the nipple far back into the baby’s mouth where the tissue is soft and the compression happens on the breast, not the nipple.
You can check the latch visually. In a good latch, your baby’s lips flare outward at a wide angle (greater than 120 degrees), and you’ll see less of the darker areola below the lower lip than above the upper lip. The chin presses into the breast. In a shallow latch, the lips barely flange open, the lower lip sits just below the nipple, and you’ll likely see equal amounts of areola above and below.
To get a deeper latch, bring your baby to the breast so their lower jaw lands well below the nipple, not right at the base of it. Tip their head slightly back so the chin leads. When the mouth opens wide, move them onto the breast quickly so the nipple aims toward the roof of their mouth. If pain starts mid-feed, that usually means the baby has slipped into a shallow position. Break the suction with your finger, reposition, and try again. One feeding with a corrected latch often produces noticeable relief.
What Works for Sore or Cracked Nipples
Once you’ve addressed the latch, damaged skin still needs time to heal. Several products are marketed for this, but the evidence behind them varies quite a bit.
Purified lanolin is the most widely recommended topical treatment. A clinical trial comparing lanolin to expressed breast milk over seven days found that lanolin nearly doubled the rate of improvement in nipple trauma: about 30% of the lanolin group showed measurable healing compared to roughly 16% in the breast milk group. You apply a thin layer after feeding without needing to wipe it off before the next session.
Expressed breast milk, often suggested as a natural remedy, performed no better than applying nothing at all in a Cochrane review of the evidence. It may offer some short-term comfort in the first few days, but the benefit doesn’t hold up over a week of use.
Hydrogel pads (glycerine gel dressings) also showed no significant improvement in pain ratings compared to standard breastfeeding education alone. Despite being popular and comfortable to wear, the clinical data doesn’t support them as a healing treatment.
Silver nursing cups are a newer option. A small randomized trial of 40 women with nipple fissures found that silver cups produced significantly faster pain resolution at both 7 and 15 days compared to standard care, with no local or systemic side effects. The cups sit over the nipple between feedings, keeping the skin moist and protected. They’re more expensive than lanolin, but the early evidence is promising for women with visible cracks or fissures.
Nipple Shields as a Temporary Fix
A thin silicone nipple shield can act as a barrier between your baby’s mouth and damaged skin, giving your nipples a chance to heal while you continue feeding. Shields are also useful if you have flat or inverted nipples that make latching difficult, or if your baby needs extra stimulation to trigger their sucking reflex.
The tradeoff is real, though. Babies may transfer less milk through a shield, which can lead to slower weight gain and reduced milk supply over time. The longer you use one, the harder weaning off it becomes. Think of a shield as a bridge to get through the worst days, not a permanent solution. If you’re using one for more than a week or two, working with a lactation consultant on the underlying latch issue will serve you better long-term.
When Pain Points to Something Else
Tongue-Tie
If you’ve worked on positioning and the latch still won’t improve, your baby’s tongue mobility may be restricted. A tongue-tie occurs when the thin tissue connecting the underside of the tongue to the floor of the mouth is too tight or attached too close to the tip, limiting how far the tongue can extend and cup the breast. The most common sign is persistent nipple pain despite correct positioning, along with a baby who seems to struggle to stay latched or makes clicking sounds during feeds. A pediatrician or lactation consultant can evaluate tongue mobility and discuss whether a simple release procedure would help.
Nipple Vasospasm
If your nipple turns white after a feeding, then shifts to blue and then red, often with sharp, burning pain, you’re likely experiencing vasospasm. This happens when blood vessels in the nipple constrict suddenly, temporarily cutting off blood flow. Cold air and a poor latch both make it worse.
The most immediate thing you can do is apply warmth right after unlatching. Press a warm cloth against the nipple or cup your hand over it to keep the tissue warm. Avoiding cold exposure (including cold rooms and cold breast pads) helps prevent episodes. Some women find relief with calcium and magnesium supplements, and for severe cases, a prescription medication that relaxes blood vessels can be very effective.
Thrush
A yeast infection on the nipple can cause persistent burning, itching, or shooting pain that continues between feedings. The skin may look red, cracked, or swollen. If your baby has a yeast infection in their mouth (oral thrush), you might notice white patches on their tongue, gums, or inner cheeks that don’t wipe away. They may also fuss during feeds because sucking is uncomfortable.
Thrush is treated with antifungal medication, which your doctor can prescribe. One reassuring finding: you don’t need to treat yourself and your baby simultaneously, and you don’t need to sterilize pump parts or toys beyond your normal cleaning routine.
Signs That Need Medical Attention
Most nipple pain resolves with latch correction and basic wound care. But certain symptoms suggest an infection that needs treatment. A fever of 101°F (38.3°C) or higher, a wedge-shaped area of redness on the breast, or visible pus from a crack or fissure can signal mastitis or a developing abscess. Mastitis that goes untreated can progress to a pus-filled pocket in the breast tissue that may need to be drained. If you notice any of these signs, getting evaluated promptly prevents the situation from escalating.
