Breastfeeding is normal and natural and is not supposed to hurt. If breastfeeding hurts at any time check through our suggestions and links below and seek help from your IBCLC lactation consultant or breastfeeding helper. Without quick help, pain during feeding can quickly cause sore or cracked nipples. And if breastfeeding hurts, because your baby isn’t attached to the breast (latched) correctly, this can reduce your milk supply leading to a baby who seems to be constantly feeding, fussing or pulling off the breast or one who isn’t gaining much weight.
Why does breastfeeding hurt?
The most likely reason for breastfeeding to hurt is when a baby attaches to the nipple without a deep mouthful of the surrounding breast tissue. If the nipple is not far enough into the baby’s mouth, it will tend to be pinched between the tongue and the roof of baby’s mouth and this will be very painful. The nipple may come out of baby’s mouth slanted like the top of a new lipstick instead of rounded like a cherry on a cake. Or nipples may even look white for a few moments as if the blood has been squeezed out of them.
Shallow latch (painful)
Latching mostly on the nipple rather than the breast is often called a shallow latch. In a shallow latch a baby’s tongue won’t be able to reach the milk ducts properly. He will find it difficult to get enough milk and breastfeeding is more likely to hurt. Babies breastfeed many times a day so it won’t take long for breastfeeding in a painful latch to lead to sore nipples including cracked or grazed nipples or blisters on nipples.
Deep latch (comfortable)
When the breast fills the mouth in a deeper latch a baby’s tongue can work properly during suckling and reach more milk. In a deep latch the nipple is protected from the painful pinch because it is deep in a baby’s mouth at the junction of the hard and soft palate.
Babies Need a Big Mouthful
While there might be some milk in your nipple, the milk is mostly in the ducts in your breast. The baby who just chews on a nipple won’t get much, and it’ll hurt! When your baby has a big mouthful of breast beyond your nipple, that’s when it’s comfortable. And that’s where the milk is. So when it feels good, it is good. As Toronto paediatrician Jack Newman often says: “It’s called breastfeeding, not nipple-feeding.”
How to get a deep latch
- Positioning your baby. The way your baby is held can make a big difference to how well he can latch on and breastfeed. In the right position your baby may automatically improve his latch and know what to do. See the articles Breastfeeding Positions for Newborns, Breastfeeding Videos and Why Skin to Skin? for ways to hold your baby so he can get a big mouthful of breast easily and get a deeper latch.
- Attaching your baby. In addition to the way you hold your baby, there are a number of techniques available to help your baby get a deep attachment. See Latching Tips for further information.
- Get help. Although pictures and videos can be helpful, the best way to check yours and your baby’s position is to see an IBCLC lactation consultant who will take a full history, and work with you one-to-one to make breastfeeding comfortable.
My health visitor says the latch looks fine, but I still have pain
Simply looking at a baby’s latch doesn’t tell the full story about what is happening to the nipple inside a baby’s mouth. If breastfeeding hurts there is still something wrong. Try to find an IBCLC lactation consultant or another breastfeeding specialist for a second opinion. It can be difficult to find the cause of the pain sometimes but painful feeding is not normal. Possible reasons for ongoing pain include:
Latch not deep enough
One helper’s idea of a good latch may be quite different from another’s particularly if they haven’t had much training in breastfeeding support. Before assuming something more complex is the cause of breastfeeding pain it can be helpful to check positioning and attachment with a specialist.
Vasospasm of the nipple is the name given for when the nipple is squeezed so tightly in a shallow latch that it squeezes the tiny blood vessels in the nipple—leading to decreased blood flow and oxygen in that area. When baby lets go of the nipple it may look white where the blood has been squeezed out of the nipple and it may look misshapen where it has temporarily been squeezed out of shape. As the blood returns to the nipple, it can be very painful causing a deep throbbing, burning type pain. For more information on causes and prevention see Nipple Vasospasm and Breastfeeding and Latching Tips.
Tension or compression from the birth
Any tension or compression from a baby’s birth may affect the nerves and muscles involved in sucking and swallowing and affect breastfeeding comfort. This could cause high muscle tone, a tight jaw, poor tongue movement or a preference for one breast over another. Forceps, ventouse or cesarean deliveries tend to be the most common causes, but sometimes even in an intervention free birth there can be physical issues due to the way a baby was positioned in the uterus. Some mothers find body work such as cranial osteopathy from a skilled therapist can improve things, particularly if their baby has had a difficult birth.
If the membrane under a baby’s tongue (the frenulum) is very short or tight it can sometimes prevent the tongue from moving properly. This can be a cause of painful breastfeeding, even with very careful positioning. For help with breastfeeding contact an IBCLC lactation consultant who can assess the range of movement in the tongue and may suggest new positions, or trying some simple tongue exercises to improve tongue function and strength to make breastfeeding more comfortable. Sometimes body work may be helpful and supervised tummy time 1 is said to help strengthen muscles involved in feeding. Your lactation consultant may recommend you see a tongue-tie practitioner to evaluate your baby’s tongue function for a procedure to release the tongue-tie (a frenotomy). See Is My Baby Tongue Tied? for further information.
Sometimes a baby who has had bottles will try to apply the way they get milk from the bottle (like sucking through a straw) to the breast—and this can cause pain. Over use of pacifiers might also cause a different suck for some babies. It can help to try to avoid bottles and dummies completely while a baby learns the right technique. If supplements are needed you could try cup-feeding or a supplemental nursing system instead. Or try using these Tips to Bottle Feed a Breastfed Baby and see Best Bottle for a Breastfed Baby to make bottle feeding more like a breastfeed. Pacifier, Dummy or Soother—Yes or No? has more information about using a pacifier.
Other causes of nipple pain
Although attachment and positioning are generally the main causes of painful feeding, other possibilities include:
Nipple infection; bacterial or fungal
Sometimes the same painful symptoms described for vasospasm or mammary constriction syndrome (see below) are due to an infection or skin condition, particularly where there has been broken skin and nipple damage. Mothers may describe a shooting, stabbing or burning pain in the nipple or breast. An infection might be bacterial, or fungal (thrush/candida/yeast) or even both at the same time. An infection may be painful and continue to be painful even with a corrected latch. For more information see Thrush on Nipples and Staph, MRSA and Breastfeeding.
Eczema, dermatitis, psoriasis
Nipples can be sore due to other medical causes unrelated to breastfeeding. The article Causes of Sore Nipples discusses eczema, dermatitis and psoriasis on the nipple as well as infections. Your doctor will confirm whether any of these could be a possibility for you and suggest treatments.
Blocked nipple pore
If a little thickened milk blocks a nipple pore (an opening in the nipple) it can sometimes be very painful. This is often called a nipple bleb or milk blister see Blisters on Nipples for more information to free the blockage if you have a painful white spot on your nipple.
Poorly fitted breast pump
If a mother pumps regularly alongside breastfeeding, a poorly fitted breast pump could be the cause of sore nipples. Pumping shouldn’t be painful but the wrong sized flange or a suction that is too high can quickly damage nipples. It is also important to make sure that the pump parts are thoroughly cleaned between feeds and not harbouring any bacteria that could contribute to infection. See How to Increase Milk Supply When Pumping for more information on choosing the right pump.
Care of nipples
Once nipples are no longer being rubbed inside a baby’s mouth thanks to optimal positioning and attachment, sore nipples usually quickly heal on their own. However sometimes sore nipples need a little help to hasten healing or conversely, a home remedy may occasionally make the situation worse. For more information see Treatments for Sore Nipples.
Nipple pain and an older baby
Sometimes nipples may begin to feel sore unexpectedly after months of pain free feeding. There can be a number of causes for this.
- Changes to positioning. It is natural to pay less attention to latching and positioning once breastfeeding is going well. Bear in mind that babies can outgrow certain positions or breastfeeding pillows and new positions may be needed.
- Teething. Sometimes when a baby is teething they may accidentally clamp down or graze the nipple. For tips to avoid this see Baby Biting While Breastfeeding. It is thought that the increase in a baby’s saliva during teething can contribute to sore nipples at this time.
- Return of periods. Some mothers notice sensitive or sore nipples around the time of ovulation or just before menstruation due to changes in hormones.
- Pregnancy. It is very common for mothers to have sore nipples when pregnant due to hormonal changes.
- Starting solids. Traces of food in a baby’s mouth may occasionally contribute to nipple soreness.
Causes of deep breast pain
Mammary constriction syndrome
Mammary constriction syndrome is a recently described syndrome related to nipple vasospasm (see above). It is described fully by Edith Kernerman, IBCLC in Dr Jack Newman’s Guide to Breastfeeding (see excerpt below) and there’s more information in Mammary Constriction Syndrome (on this website).
Because of difficulties the mother may have had during pregnancy, labour, or after birth, she may have tightness in her shoulders and chest that causes her pectoral (chest) muscles to press on the blood vessels that lead to her breasts and nipples, causing a lack of blood flow and oxygen, leading to pain. This pain may be throbbing or constant, deep or superficial, itchy, tingling, aching or knife-like, burning or freezing, shooting, sharp or dull, or a combination of any of the above. Also, if a latch feels painful, the mother may tighten her shoulders, clench her teeth, etc., causing the cycle triggering pain to begin again.
Engorgement, mastitis or a blocked duct
There are several potential causes for your breasts becoming full and tender and uncomfortably engorged (over full of milk). If this happens at any stage it’s important to feed your baby often or pump to drain the breasts to resolve the engorgement and avoid possible mastitis. Mastitis is a very painful inflammation of the breast. Check the suggestions in our articles Engorged Breasts, Blocked Milk Duct and Mastitis Symptoms and Treatment and ask your IBCLC lactation consultant for help with breastfeeding to understand what caused the engorgement and prevent it happening again.
Protect your milk supply while you work on making breastfeeding pain free
Whenever there is pain and a poor latch there is a chance that your breast milk supply may drop and that your baby won’t be getting enough milk. Expressing after feeds by hand expressing or pumping will keep your breasts well drained and so stimulate your breast milk supply. The expressed breast milk can be fed back to your baby after a breastfeed as needed (by spoon, cup, syringe, bottle or supplementary nursing system). Continuing to get regular weights (weekly, or more often if needed until breastfeeding is pain free) will help to gauge how much milk your baby is getting and see Is My Baby Getting Enough Milk?

There are several reasons why breastfeeding might hurt. The most common reason for breastfeeding to hurt is if a baby isn’t latched correctly leading to sore or damaged nipples, deep breast pain or both. Once cracked or grazed, nipples are more susceptible to infections, another possible cause of ongoing pain. Your breastfeeding specialist can help to find the most likely reason for pain alongside your health professional who will check for medical causes.
