Breastfeeding Pain: Causes, Fixes, and When to Call a Lactation Consultant

Breastfeeding should not be painful. That's one of the most important things a new mom can hear — because pain is also one of the most common reasons moms stop breastfeeding earlier than they'd like.

The good news: most breastfeeding pain has a clear cause and a real fix. Whether you're dealing with sore nipples, cracked skin, or pumping discomfort, here's what's likely happening and what you can do about it.

Is It Normal for Breastfeeding to Hurt?

Some mild tenderness in the first few days is common as your body adjusts. But sharp, persistent nipple pain — the kind that makes you dread each feeding — is a signal that something needs attention. It's your body asking for a change, not a rite of passage you have to push through.

The Most Common Causes of Breastfeeding Pain (And How to Fix Them)

1. A Shallow Latch

A poor latch is the number one cause of nipple pain in breastfeeding. When a baby latches onto just the nipple instead of a full mouthful of breast, friction and compression create pain quickly.

Signs of a good latch:

• No sharp pain after the first few seconds
• Baby's lips are flanged outward (think "fish lips"), not tucked in
• More of the areola is visible above baby's lips than below

Two techniques that help:

The Flipple Technique: Bring baby's chin to the breast first. Point your nipple toward baby's nose, wait for a wide-open mouth, then roll the breast and nipple in together. This encourages a deeper latch from the start.

Laid-Back Breastfeeding: Recline in a supported position — not flat, but comfortably back, with your head and shoulders supported. Place baby chest-to-tummy on top of you, cheek near the breast, and let gravity and instinct do the work. This position is especially great for skin-to-skin time and can feel like a reset when other positions aren't working.

2. Dry, Cracked, or Split Nipples

Cracked nipples are most common in the newborn stage and are usually tied back to latch — but they can persist even as latch improves. The skin needs support to heal between feedings.

What helps:

• Express a few drops of breast milk after each feeding and let it air dry on your nipple. Breast milk has natural healing properties and is completely safe for baby.
• Apply a food-grade oil between feedings — coconut, olive, or grapeseed oil are all gentle options that don't need to be wiped off before nursing.
• Keep nursing pads dry. Moisture creates the perfect environment for bacteria and yeast. Change wet pads promptly and opt for breathable fabrics over synthetic ones. Thrush (a yeast infection that affects both nipples and baby's mouth) is more common than most moms expect, and keeping things dry is one of the best ways to prevent it.

3. Wrong Pump Flange Size

This one gets overlooked constantly — and it matters more than most people realize. Flanges (the cone-shaped parts of your breast pump that fit over your nipple) are not one-size-fits-all, and many moms are pumping with the wrong size.

• Too small: Creates friction and irritation on the nipple
• Too large: Doesn't create the right vacuum seal, leading to poor milk removal and discomfort

Most moms will also fluctuate between flange sizes throughout their pumping journey as their body changes. Measuring periodically — especially after the first few weeks postpartum — is worth doing.

When to Contact a Lactation Consultant

If you've tried the steps above and pain continues, please reach out to an IBCLC (International Board Certified Lactation Consultant). They can assess your baby's latch in person, check for tongue or lip ties, rule out infection, and give you personalized support that a blog post simply can't replicate.

Getting the support side right — the right latch, the right flange size, and yes, the right clothes — makes the whole journey easier. Nursing-friendly tops and dresses that give you quick, discreet access mean one less thing to wrestle with when every feeding counts.
