Cracked & Bleeding Nipples: Causes, Treatment & When to Worry
Nipple pain is common in early breastfeeding — but common doesn't mean you should just push through it. Here's what's usually behind it, what helps, and when it's time to call a professional instead of trying another home remedy.

Common Causes
Cracked or bleeding nipples almost always have an identifiable cause — it's rarely just "bad luck." Here are the ones that come up most often:
Latch issues
A shallow or poor latch is the single most common cause of nipple damage in the first weeks. If pain continues throughout the whole feed, or your nipple looks compressed, creased, or a different shape right after feeding, latch is the first thing to check — see the section below for specific signs.
Incorrect pump flange size
The same friction mechanism as a bad latch, but from pump equipment instead of baby. If cracking only happens on the side you pump more, or coincides with when you started pumping, flange fit is worth checking — see our full guide to pumping nipple pain for how to check it.
Nipple thrush (yeast infection)
Traditionally diagnosed based on burning pain that continues even with a good latch, sometimes with pink, shiny, or flaky skin. Worth knowing: recent research has actually questioned whether "nipple thrush" is a real, distinct diagnosis at all — some breastfeeding medicine specialists now attribute these symptoms to dermatitis or other skin issues instead. Either way, persistent burning pain that doesn't improve with a good latch is a reason to see a doctor or IBCLC for an actual diagnosis, not to self-treat with antifungal cream and hope.
Tongue-tie or other oral restrictions in baby
If latch looks correct by every visual sign but pain continues and doesn't improve with positioning changes, a tongue-tie or lip-tie assessment from a pediatrician or IBCLC is worth pursuing — this isn't something you can diagnose from a symptom checklist alone.
Is It a Latch Problem?
Since latch is by far the most common cause, it's worth checking specifically before assuming anything else. A few signs point toward latch as the culprit:
- Pain is present for the entire feed, not just the first few seconds before it "warms up"
- Your nipple comes out flattened, creased, or a different shape (like a new lipstick shape) right after feeding, instead of round
- You can hear clicking sounds during feeding, or your baby's cheeks dimple in while sucking
- Pain changes when you adjust positioning — even a small shift making it noticeably better or worse is a strong sign the latch itself is the variable
If any of these sound familiar, the most effective next step isn't a product — it's a latch check. A lactation consultant can usually spot the specific issue (positioning, tongue function, or something else) in a single visit, and fixing it addresses the pain at the source rather than managing it feed after feed. We're not going to pretend a cream or a cup fixes a latch problem, because it doesn't — they help the skin recover while you work on the actual cause.
- Breast that's red, hot, swollen, or tender to the touch (possible mastitis)
- Fever, chills, body aches, or flu-like symptoms
- Pain that continues even between feeds, not just during them
- Yellowish discharge from the nipple resembling colostrum, outside of normal milk
- A crack or wound that isn't healing after a week or more despite a corrected latch

When It's Normal vs. When to Worry
- First few days: Mild tenderness at the start of a feed that eases within the first minute is common as you and your baby are both learning. This is the closest thing to "normal" in this whole list.
- First 1-2 weeks, pain persisting or worsening: Not something to just wait out — this is the window to get a latch check if you haven't already, since damage tends to compound the longer a poor latch continues.
- Pain that suddenly returns after weeks of comfortable feeding: Worth a specific look — this pattern is more associated with thrush, a new positioning issue, or your baby's teeth/oral development changing, than with a latch problem you already solved.
- Any of the red-flag signs above: Not a "wait and see" situation — contact your doctor.
Treatment, In the Right Order
The order matters more than which specific product you pick:
- Fix the mechanical cause first — a latch check (in person or virtual with an IBCLC) if latch is the likely cause, or a flange resize if you're pumping. This is free or low-cost and addresses the actual source.
- Support healing between feeds — this is where lanolin, hydrogel pads, or reusable silver cups come in. They don't fix the cause, but they protect already-damaged skin while it recovers. See our comparisons: Silverette vs. Lanolin and Silverette vs. Hydrogel Pads for how each approach compares.
- Escalate if it's not improving — if pain hasn't started improving within a few days of fixing the latch and using a supportive product, that's a sign to loop in your doctor rather than trying yet another home remedy.
Reusable silver cups like Silverette are one option some mothers use for step 2 — worn between feeds, no reapplying cream throughout the day. See our full Silverette review for how they work and what independent reviewers found. They're a comfort and protection measure, not a substitute for addressing why the cracking started in the first place.
Per La Leche League GB and multiple lactation health sources, nipple or breast pain is not considered a normal, expected part of breastfeeding — persistent pain almost always has an identifiable, addressable cause. If something here sounds like your situation and isn't improving, reaching out to an IBCLC is one of the highest-value things you can do in those early weeks.
FAQ
Is it normal for nipples to bleed a little while breastfeeding?
A small amount of blood from nipple trauma won't harm your baby if swallowed, but bleeding itself isn't something to consider "normal" or ignore — it's a sign of skin damage that has an underlying cause worth addressing, most often latch.
How long does it take for cracked nipples to heal?
Once the underlying cause (usually latch) is corrected, visible improvement often starts within a few days, with fuller healing over one to two weeks. If you're not seeing improvement within about a week of fixing the cause, that's worth discussing with a doctor or IBCLC rather than waiting longer.
Can I keep breastfeeding if my nipples are cracked?
Generally yes — most sources note you can continue breastfeeding through nipple trauma unless the pain becomes unbearable, though fixing the underlying cause (usually latch) matters more than pausing. If you're unsure given your specific situation, check with your doctor or IBCLC.
Is nipple thrush a real diagnosis?
It's genuinely debated among breastfeeding medicine specialists. Some recent research questions whether "nipple thrush" as traditionally diagnosed is accurate, suggesting dermatitis or other skin conditions may explain the same symptoms in many cases. Either way, persistent burning pain not explained by latch is worth a professional diagnosis rather than self-treating.
