Sore nipples in the first week of breastfeeding are common, but they should improve quickly. Pain that lasts beyond the first week or continues throughout an entire feeding is not normal and signals something needs to change. The good news: most nipple soreness comes down to how your baby latches, and fixing that one thing often resolves the problem entirely.
Why Breastfeeding Hurts
The most common cause of sore, cracked, or bleeding nipples is a shallow latch. When your baby only takes the nipple into their mouth instead of a large portion of the areola, the nipple gets compressed against the hard palate with every suck. That repeated friction and pressure creates pain, cracks, and sometimes blisters.
Other causes include tongue-tie in your baby (a tight band of tissue under the tongue that restricts movement), thrush (a yeast infection shared between your nipple and baby’s mouth), and nipple vasospasm, where blood vessels in the nipple clamp down and cause sharp, burning pain. Each of these feels different, which helps you figure out what’s going on.
How to Fix a Shallow Latch
A good latch means your baby’s mouth covers not just the nipple but about 1 to 2 inches of areola, with more areola visible above the top lip than below the bottom lip. This asymmetrical positioning places the nipple deep in the mouth against the soft palate, where it won’t get compressed.
To get there, start by lining up your baby so their ear, shoulder, and hip form a straight line. Use a nursing pillow or a small stool under your feet so you can bring baby to breast height without hunching forward. Hold your breast in a C-shape, like you’re holding a sandwich, and aim your nipple just above your baby’s top lip, toward their nose. Let the nipple gently brush their upper and lower lip until their mouth opens wide. When it does, bring them onto the breast chin-first. Their lower lip should land well below the nipple, their lips should flare outward like a fish, and their chin should press into the lower part of your breast.
If the latch feels painful, don’t just endure it. Break the suction by sliding your finger into the corner of your baby’s mouth, then try again. A correct latch may feel like strong tugging, but it should not feel like pinching or biting.
What Helps Sore Nipples Heal
Once you’ve addressed the latch, your nipples still need time to recover. Several options can speed that along.
Hydrogel Pads
In a clinical trial of 106 breastfeeding mothers, hydrogel dressings provided significantly better pain relief than lanolin ointment. Women using hydrogel pads also discontinued treatment sooner, suggesting faster healing. Notably, the lanolin group had eight breast infections during the study while the hydrogel group had none. These pads are placed directly over the nipple between feedings and create a moist wound-healing environment.
Medical-Grade Lanolin
Highly purified lanolin still has its place. One controlled trial of 84 mothers found that medical-grade lanolin, combined with breastfeeding education, healed nipple trauma faster and reduced pain more effectively than applying expressed breast milk alone. Apply a thin layer after each feeding. You don’t need to wipe it off before the next feed.
Silver Nursing Cups
Silver has natural antimicrobial properties. Silver ions disrupt bacteria on damaged skin, which can help prevent infection while your nipples heal. Small cup-shaped shields sit inside your bra between feedings. Wearing them for no more than 12 hours a day is generally recommended.
Simple Comfort Measures
Let your nipples air-dry after feeding rather than wiping them. Avoid soap on the nipple and areola, which strips natural oils. If your nipples stick to bra pads, dampen the pad before removing it to avoid tearing healing skin. Cool compresses after a feed can ease swelling, and warm compresses before a feed can help with let-down if you’re tensing up from pain.
When the Problem Isn’t the Latch
If you’ve corrected your latch and pain persists, something else may be at play.
Tongue-Tie
A tight piece of tissue under your baby’s tongue can prevent them from extending their tongue far enough for a deep latch, no matter how well you position them. The telltale sign is a nipple that comes out of your baby’s mouth misshapen, often flattened like a new lipstick or with a white stripe across the tip. You may also see cracks, creases, or blisters that keep returning despite latch corrections. A lactation consultant or pediatrician can evaluate whether a tongue-tie is the cause.
Thrush
A yeast infection on the nipple often shows up as pink, shiny, or flaky skin on the nipple and areola. The pain tends to feel like burning, and it can radiate deeper into the breast. One hallmark is pain that seems out of proportion to what your nipples look like. Your baby may also have white patches inside their mouth. Thrush requires treatment for both you and your baby to prevent passing it back and forth.
Vasospasm
If your nipple turns white (blanches) after a feed and then shifts to purple or red, accompanied by shooting or burning pain, you’re likely dealing with vasospasm. This happens when blood vessels in the nipple constrict, temporarily cutting off blood flow. It’s more common in cold environments. Some women notice it after stepping out of a warm shower or walking through the frozen food aisle. If you have a history of cold hands and feet, or a condition like Raynaud’s syndrome, you’re at higher risk. Keeping your chest warm and applying dry heat to the nipple immediately after feeding can reduce episodes.
Prescription Options for Severe Damage
For nipples that are deeply cracked, infected, or not responding to over-the-counter treatments, a healthcare provider may prescribe a compounded nipple ointment. These typically combine an antibiotic to fight skin bacteria, a mild steroid to reduce inflammation, and an antifungal to address yeast. The ointment is applied sparingly after feedings and left on. An over-the-counter version using hydrocortisone and an antibiotic ointment mixed in equal parts is sometimes suggested as a first step, though the prescription version is more targeted.
Signs of a More Serious Problem
Cracked nipples create an entry point for bacteria, and sometimes that leads to mastitis, an infection of the breast tissue. Watch for breast swelling, warmth, or tenderness that goes beyond normal engorgement. A wedge-shaped area of redness on the breast is a classic sign (though on darker skin tones, this may appear as a change in texture or warmth rather than visible redness). Fever of 101°F or higher, feeling flu-like, or a hard lump in the breast alongside these symptoms points toward an infection that needs prompt medical treatment.
How Long Soreness Should Last
Initial nipple tenderness typically resolves within about one week as your skin adapts and your latch improves. Pain that continues past that first week, or pain that lasts throughout an entire feeding rather than just the first few seconds, is your signal to get hands-on help. A lactation consultant can watch a feeding in real time and spot subtle latch or positioning issues that are hard to identify on your own. Many hospitals, birthing centers, and WIC offices offer free or low-cost lactation support.
