Breastfeeding Shouldn’t Hurt: What Nipple Pain Is Telling You

Breastfeeding is something you and your baby are learning together, and sometimes that learning comes with a little tenderness. However, if every latch makes you brace yourself, curl your toes, or wonder how you are going to get through the next feed, I want you to know that you do not have to simply push through. Persistent pain is your body’s way of giving us information. It may be telling us something about latch, positioning, milk transfer, oral function or the way your nipples are responding to feeding. As an IBCLC, my goal is to listen to what you are feeling, understand what your pain is telling us, and work alongside you to make feeding more comfortable and sustainable.

First, what is normal and what isn’t

Mild tenderness in the first seconds of a latch during the first week is common and should completely ease as the feed goes on. 

These aren’t normal, and none of them improve by waiting:

• Pain that continues throughout the entire feed
• Cracked, blistered or bleeding nipples
• A nipple that comes out of your baby’s mouth creased, flattened or wedge-shaped
• Burning or shooting pain between feeds
• Pain that starts after weeks of comfortable feeding

That last one matters. New pain in an established feeding relationship usually has a new cause, and it’s worth investigating rather than assuming something has gone wrong with you.

The most common cause: a shallow latch

Most nipple pain traces back to latch depth. If your baby’s mouth closes near the tip of the nipple rather than taking a good portion of the underlying breast tissue, the nipple gets compressed against the hard palate with every suck. That compression is what cracks skin and creases nipples.

A deeper latch usually comes from a few small adjustments:

• Line your baby up nipple to nose, so they have to tip their head back slightly to reach.
• Wait for a wide gape, as wide as a yawn, before bringing them on.
• Bring your baby to you, lead with the chin making contact first.
• Keep your baby’s body in a straight line, ear, shoulder and hip aligned, tummy against you.

Worth knowing: when the latch is deep enough, your nipple should come out of your baby’s mouth round and unchanged. A lipstick shape or a crease across the tip is one of the clearest signs that the latch needs adjusting.

When the latch looks fine and it still hurts

This is the point where a lot of parents get stuck, because the usual advice runs out. Several other causes look similar from the outside:

Restricted tongue movement. If your baby can’t lift or extend their tongue well, they may not be able to hold a deep latch even in a good position. Clicking sounds, sliding off repeatedly, milk leaking at the corners of the mouth and feeds that never seem to end are worth assessing. Function matters more than appearance here, which is why an oral assessment during an actual feed is more useful than a photograph.

Vasospasm. If your nipple blanches white after a feed and then changes colour, and you feel a burning or throbbing pain that’s worse in the cold, this is likely vasospasm. It’s often triggered by compression from a shallow latch or a poorly fitting flange, so the first step is fixing the compression. Warmth immediately after feeds, rather than air-drying, usually helps.

Flange fit. If you pump, the wrong tunnel size causes exactly the same pain pattern as a shallow latch: rubbing, blanching, soreness and lower output. Sizing is based on nipple diameter at the tip. I cover this in detail in my post on breast pump and flange fitting consultations.

What to do tonight while you wait for help

• Feed from the less painful side first if one side is worse, then switch once letdown is underway. Continue to work on deep latch technique.
• If a feed is unbearable, hand express or pump on that side for a session rather than pushing through. Milk needs to keep moving, but not at the cost of further damage.
• Apply a few drops of your own milk to the nipple after feeding sessions and let it air dry before covering
• Take a look at the nipple shape immediately after unlatching. That one observation tells me a lot.

When it’s more than nipple pain

Contact your healthcare provider the same day if you have a fever, chills or flu-like aching along with a red, wedge-shaped, tender area on the breast. That combination suggests infection.

Current guidance on mastitis has changed a good deal in recent years and much of what is still circulating online is out of date. Deep massage, heat and attempts to “empty” the breast can make inflammation worse. Cold, lymphatic massage, anti-inflammatories where appropriate and continuing to feed normally are the current approach. If you’re dealing with recurring blockages or mastitis, that pattern is worth investigating properly rather than treating episode by episode.

Getting it sorted properly

Nipple pain is one of the most common reasons families call me, and it’s also one of the most fixable. What I need to see is a full feed: how your baby latches, how they transfer milk, what your nipple looks like afterwards, how your baby’s tongue moves, and if you pump, how your equipment fits.

I offer IBCLC consultations in your home across Ottawa, including Kanata, Barrhaven, Orléans, Stittsville, Riverside South, Findlay Creek, Manotick Village, Hintonburg, The Glebe and Aylmer, and virtually to families across Canada. Every consultation includes a flange fit assessment if you pump, a written care plan, and a week of follow-up messaging.

You don’t need to prove that the pain is bad enough to warrant help. If feeding hurts, that’s reason enough.

Related questions

How long should breastfeeding hurt at the beginning?

Mild tenderness at the start of a latch is common in the first week and should settle by around two weeks. Pain that lasts the whole feed, damages skin, or appears after weeks of comfortable feeding always has a cause worth identifying.

Why do my nipples turn white after feeding?

Blanching followed by a colour change and burning pain usually indicates vasospasm.

Can I keep breastfeeding with cracked nipples?

Usually yes, and continuing to remove milk matters. However, if a feed is causing further damage, expressing on that side for a session or two while we correct the underlying cause is a reasonable short-term plan rather than a setback.

Do I need a nipple shield?

Sometimes, in specific situations, however, a comprehensive assessment is a key piece in this. We want to get to the root of the concerns first and then determine interventions tailored to you.
