Nobody warns you quite thoroughly enough.
You’ve read the books, attended the classes, watched the videos. You know breastfeeding might be “a little uncomfortable at first.” What nobody quite prepares you for is sitting in a hospital chair at two in the morning, gripping the armrest through a feed, wondering how something so natural can possibly hurt this much.
Nipple pain is one of the most common reasons mothers stop breastfeeding before they want to. It is also one of the most misunderstood — because not all nipple pain is the same, not all of it is inevitable, and almost all of it has a cause that can be identified and addressed.
This post is here to help you understand what’s normal, what isn’t, and most importantly — what to do about it.
Is Some Nipple Pain Normal?
Yes. But only some, and only for a limited time.
In the very first days of breastfeeding, as your nipples adjust to a level of use they have never experienced before, some tenderness is entirely normal. Many mothers describe a sharp or intense sensation at the moment their baby latches — what’s often called “latch pain” — which typically peaks in the first few seconds and then eases as the feed continues.
This initial tenderness usually improves noticeably by the end of the first week and should be largely resolved by two weeks. It is uncomfortable. It is not pleasant. But it is generally manageable, it follows a predictable pattern, and it gets better.
What is not normal — and what should never be dismissed as “just part of breastfeeding” — is pain that:
- Is severe from the start and doesn’t ease during the feed
- Persists throughout the entire feed rather than easing after the first minute
- Continues or worsens beyond the first two weeks
- Causes nipple damage — cracking, bleeding, blistering, or scabbing
- Wakes you from sleep or makes you dread the next feed
- Occurs between feeds as well as during them
If any of these describe your experience, something is wrong and it deserves attention. Pain at this level is not something to push through. It is your body telling you that something about feeding mechanics — or something else entirely — needs to be looked at.
What Causes Nipple Pain?
There is almost always a cause. Here are the most common ones.
1. A Shallow or Incorrect Latch
This is the most frequent cause of nipple pain in breastfeeding, and it’s the first thing any feeding assessment should look at.
When a baby latches shallowly — taking only the nipple rather than a good mouthful of breast — the nipple is compressed against the hard palate at the top of the mouth with every suck. This is painful in the way that pressing a finger repeatedly against a hard surface is painful: it causes friction, compression damage, and over time, significant trauma to the tissue.
A well-latched baby takes a large mouthful of breast, with your nipple positioned far back in the mouth against the soft palate where it isn’t compressed during feeding. When the latch is right, feeding should be comfortable.
Signs that a shallow latch may be the issue:
- Pain that lasts throughout the entire feed
- Nipples that come away from feeds looking flattened, wedge-shaped, or lipstick-shaped
- You can hear your baby clicking during feeds
- Your baby slips off the breast frequently or struggles to stay latched
- The pain is worse on one side than the other
A shallow latch is almost always correctable with hands-on support. But it can also be caused or maintained by physical factors — which brings us to the next point.
2. Tongue Tie
Tongue tie is one of the most common and most frequently missed causes of nipple pain, and in my experience it is responsible for a significant proportion of the cases I see where pain simply isn’t improving despite efforts to adjust latch and positioning.
When a baby has a restricted tongue, they cannot create the wide, cupped latch that comfortable breastfeeding requires. Instead, they compensate — often by clamping with their gums, gripping with their lips, or using a chewing motion rather than a proper rhythmic suck. All of these create pressure and friction on the nipple that leads to pain and damage.
Tongue tie — particularly posterior tongue tie, which sits further back under the tongue and is easily missed — will not resolve on its own, and no amount of repositioning will fully compensate for a tongue that physically cannot move the way it needs to.
If your nipple pain is persistent, if your nipples are being damaged despite attempts to improve latch, or if a shallow latch keeps recurring no matter what you try, tongue tie should be assessed. See my dedicated Tongue Tie page for more.
3. Nipple Thrush
Thrush is a yeast infection caused by the organism Candida albicans, which can colonise nipple and breast tissue and cause a very distinctive type of pain.
Unlike the compression pain of a poor latch — which tends to be worst during the feed itself — thrush pain is characterised by burning, itching, or shooting sensations in the nipple and breast, often continuing or worsening after the feed ends. Some women describe it as a deep, stabbing pain in the breast, or a feeling like shards of glass or hot needles.
Signs that thrush may be involved:
- Burning, itching, or shooting pain in the nipple or breast during or after feeds
- Pain that appeared after a period of pain-free feeding
- Nipples that look shiny, flaky, or unusually pink
- White patches in your baby’s mouth (though not always present)
- Recent antibiotic use by you or your baby — antibiotics disrupt the normal bacterial balance that keeps yeast in check
- A nappy rash in your baby that isn’t responding to normal treatment
Thrush requires treatment for both you and your baby simultaneously, even if only one of you has visible symptoms. Treatment is usually an antifungal cream for your nipples and oral drops for your baby’s mouth. If you suspect thrush, see your GP — it won’t resolve without treatment.
4. Bacterial Infection
Less common than thrush but worth being aware of, a bacterial infection of cracked or damaged nipple skin can cause significant pain. If you have visible nipple damage — particularly cracks or open sores — these create an entry point for bacteria.
Signs of bacterial infection include:
- Nipple wounds that are weeping, crusting, or not healing as expected
- Skin around the nipple that is red, warm, or swollen
- Increased pain in a wound that was previously improving
- Fever or flu-like symptoms — which may suggest the infection has spread into the breast tissue (mastitis)
If you suspect a bacterial infection, see your GP. A swab of the wound can identify the specific bacteria and guide appropriate antibiotic treatment.
5. Vasospasm and Raynaud’s Phenomenon
Vasospasm — a sudden contraction of the blood vessels in the nipple — causes a very recognisable pattern of pain that many mothers never connect to its actual cause.
After a feed, or when the nipple is exposed to cold (including the air), the nipple suddenly blanches — turning white, then sometimes cycling through blue and red — accompanied by intense burning, throbbing, or aching pain. This is caused by a sudden reduction in blood flow to the nipple tissue.
Raynaud’s phenomenon of the nipple is essentially the same process, often affecting people who already experience Raynaud’s in their fingers or toes, though it can occur in breastfeeding women without any prior history.
Signs that vasospasm may be involved:
- Pain that occurs after the feed ends, often when the nipple cools
- Visible colour change in the nipple — white, blue, or red in sequence
- Burning or throbbing rather than compression-type pain
- Improvement when the nipple is kept warm immediately after feeding
Vasospasm can be triggered or worsened by a poor latch, so addressing latch should always be the first step. Keeping the nipple warm immediately after feeds — by covering quickly, using a warm compress, or wearing a soft nipple cover — can help significantly. In some cases, medication may be recommended by your GP.
6. Engorgement
In the first few days after birth, as your milk comes in, many women experience significant engorgement — breasts that feel hard, heavy, swollen, and painful. This is normal, but severe engorgement makes it harder for your baby to latch, which can in turn cause nipple pain and damage.
Feeding frequently — at least every two to three hours — is the most important thing you can do to manage engorgement. Gentle breast massage before and during feeds, hand expression to soften the areola before latching, and cool compresses between feeds can all help.
Engorgement that is severe or prolonged, or that is accompanied by fever, may indicate mastitis — see your GP.
7. Oversupply and Forceful Letdown
If your milk flows very fast and forcefully, your baby may struggle to cope with the pace and resort to clamping the nipple to slow the flow. This creates significant pain and can cause the same compression damage as a shallow latch.
Signs of forceful letdown:
- Your baby coughs, splutters, or pulls off the breast when milk lets down
- Your baby seems to gulp and swallow frantically at letdown
- You notice milk spraying forcefully when your baby unlatches
- Your baby is very gassy and uncomfortable despite frequent feeds
Oversupply and forceful letdown can be managed — but require a careful, graduated approach. Getting the balance right matters, and IBCLC-level support is genuinely useful here.
What Your Nipples Are Telling You
The shape your nipples come away from feeds in can tell you a great deal about what’s happening mechanically.
Lipstick-shaped or wedge-shaped nipple: This is one of the clearest signs of compression damage. If your nipple looks like the end of a tube of lipstick — flattened on one side, angled — it means the nipple is being pressed against a hard surface during feeding. This is almost always a latch or tongue function issue.
Creased across the tip: A horizontal crease across the nipple tip suggests the nipple is being pinched between the baby’s tongue and palate rather than sitting comfortably against the soft palate.
Blanched (white) after feeds: This points strongly towards vasospasm, particularly if accompanied by burning pain.
Blistered, cracked, or bleeding: Any visible damage to the nipple skin needs to be assessed. Keep wounds clean, apply a thin layer of medical-grade lanolin or expressed breast milk after feeds to support healing, and seek support — open wounds don’t heal while the trauma causing them continues.
Looking After Your Nipples
While you’re working on identifying and addressing the cause of your pain, a few things can help protect your nipples and support healing:
- Apply expressed breast milk after feeds — breast milk has natural antimicrobial and healing properties and can be applied directly to the nipple after each feed
- Use medical-grade lanolin — a small amount applied after feeds keeps the nipple moist and supports healing without needing to be washed off before the next feed
- Avoid soap on your nipples — soap strips the natural oils from the skin and slows healing
- Let nipples air dry briefly after feeds where possible
- Wear soft, breathable fabrics — synthetic fabrics trap moisture and increase the risk of fungal overgrowth
- Check your breast pads — change them frequently and avoid pads with plastic backing that trap moisture
- Consider nipple shields only with professional guidance — shields can be genuinely helpful in certain situations but can also create new problems if used without support, and they should be seen as a temporary bridge rather than a permanent solution
When to Seek Help
The honest answer is: sooner rather than later.
Nipple pain that isn’t improving in the first week, pain that involves visible nipple damage, pain that makes you dread feeding, or pain that continues beyond two weeks all warrant a feeding assessment. The longer pain persists without being addressed, the greater the risk to your milk supply and to your breastfeeding relationship.
You should also see your GP promptly if you have signs of thrush, bacterial infection, or mastitis — these need medical treatment that a lactation consultant alone cannot provide.
And if you’ve been told “your latch looks fine” but you’re still in pain — please seek a second opinion. Latch assessment requires watching a full feed carefully and examining your baby’s oral anatomy and function. A quick glance doesn’t constitute a full assessment, and pain that isn’t being taken seriously deserves someone who will take it seriously.
You Don’t Have to Hurt to Feed Your Baby
I’ll say it plainly, because it often needs saying: breastfeeding should not be consistently painful. Initial tenderness, yes. Persistent, severe, or worsening pain — no.
If you are in pain, there is a reason. That reason can almost always be found. And in the vast majority of cases, with the right support, it can be resolved.
You don’t have to choose between breastfeeding and being comfortable. With the right help, you can have both.
