Why Does Breastfeeding Hurt (and When Should I Worry)? by Shannon Pratten, RN, IBCLC & Founder of Milk Drunk Club

Breastfeeding can come with some tenderness in the beginning — but ongoing pain is not normal. In this post, NICU RN and IBCLC Shannon Pratten breaks down why breastfeeding hurts, what’s considered normal in the early days, and the red flags that signal something deeper like a shallow latch, oral ties, thrush, vasospasm, or early mastitis. You’ll learn how to troubleshoot the most common causes, when to ask for help, and why pain is a sign to adjust, not something you should “push through.” Feeding your baby shouldn’t feel like a battle — here’s how to make it comfortable, sustainable, and stress-free again.

Let’s start with the truth no one likes to say out loud:
Sometimes breastfeeding hurts — and it shouldn’t stay that way.

In the early days, you might feel tenderness, sensitivity, or the occasional toe-curling latch. But ongoing pain? Cracks? Bleeding? That’s your body’s way of saying, “Hey, something’s off.”

You deserve comfort, not endurance.


The Difference Between “Normal” and “Not Normal”

A little nipple tenderness in the first week or two can be normal — your body’s adjusting to 24/7 use of a part that previously just… existed quietly under a shirt.

But pain that lingers or worsens after those early days isn’t part of the deal. Here’s the quick breakdown:

Sensation Likely Normal Needs Attention
Initial tenderness that fades after latch
Sharp, burning, or stabbing pain during or after feeds 🚨 Possible latch issue or infection
Cracked, bleeding, or scabbed nipples 🚨 Shallow latch or oral restriction
One-sided pain or wedge-shaped nipple blanching 🚨 Vasospasm or tongue tie
Deep breast ache, redness, or fever 🚨 Mastitis or blocked duct

💡 IBCLC tip: Pain is a symptom, not a sign of weakness. If it doesn’t improve quickly, get support — don’t “tough it out.”


Common Culprits (and How to Fix Them)

1️⃣ Shallow latch:
If baby’s lips aren’t flanged wide or you feel pinching, unlatch and try again. Think nose to nipple and bring baby to you, not the other way around.

2️⃣ Tongue or lip tie:
Restricted movement under the tongue or lip can make deep latching difficult. If you’ve tried adjusting position with no improvement, get an oral assessment — preferably by a team familiar with infant feeding (IBCLC + pediatric dentist or CST trained in oral ties).

3️⃣ Engorgement or oversupply:
Rock-hard breasts make it tricky for baby to latch deeply. Hand express a little first to soften the area and help baby get a better mouthful. Or try reverse pressure softening. 

4️⃣ Thrush or vasospasm:
If you feel burning, itching pain on both sides even between feeds, or your nipples look white or shiny, call your provider. These issues are medical — not “just in your head.”


The Emotional Side of Pain

Here’s the part few people say: breastfeeding pain doesn’t just hurt physically — it can rattle your confidence.
You might start dreading feeds, questioning your ability, or feeling resentment instead of connection.

That doesn’t mean you’re failing. It means you’re human.

Pain steals the joy out of something meant to feel peaceful — and that’s exactly why addressing it matters.


When to Get Help

If pain lasts more than a few days, if you’re bleeding, or if baby isn’t gaining weight well — reach out. An IBCLC can help assess latch, positioning, and oral anatomy.

You shouldn’t have to “push through.” This is not a marathon of suffering.
It’s a relationship — and like any good one, it needs balance and comfort on both sides.
