Sore is common. Pain is not normal.

In the first days of breastfeeding, some tenderness is expected as your body adjusts. Nipple tissue is delicate and it takes time to toughen up. But pain that makes you dread feeding, lasts through the whole feed, or continues afterward is not something to push through — and it's almost always fixable once you know the cause.

The fastest way to narrow it down: pay attention to when it hurts and what it feels like. Different causes produce different pain patterns, and matching the pattern to the cause gets you relief faster than trying random remedies.

Match your pain to a cause

Sharp pain while latching (latch issues)

The most common cause of nipple pain, accounting for about 80% of cases. Baby needs a deep, asymmetric latch — not just the tip of the nipple. In a good latch, the nipple goes far back into baby's mouth, near the soft palate, and the areola is mostly inside too.

Signs of a shallow latch:

• Baby's lips are pursed (like a kiss) instead of flanged outward
• You can see more than a few millimeters of the areola above baby's mouth
• Baby's chin isn't touching the breast
• Pain starts at latch and continues through the feed
• Nipple comes out looking pinched, like a new lipstick tube

How to fix it:

• Wait for baby to open really wide — like a yawn — before latching
• Tilt baby's head back slightly so the chin leads
• Bring baby to the breast, not the breast to baby
• Try laid-back (biological nurturing) position — gravity helps baby get a deeper latch
• If pain doesn't improve within 24–48 hours, get a latch assessment from an IBCLC

Cracked, raw, or bleeding

This is usually nipple trauma from a shallow latch or a tongue tie. The skin breaks down from friction and pressure, and can progress to bleeding if the cause isn't fixed.

What to do:

• Keep feeding on your schedule — suddenly stopping leads to engorgement and can make things worse
• Start feeds on the less painful side first, then switch to the sore side when baby's sucking is gentler
• After feeding, express a little colostrum or milk and rub it on the nipple — it has healing properties
• Let nipples air-dry after feeds — don't put on a bra immediately
• Use medical-grade lanolin or hydrogel pads between feeds for comfort
• Avoid soap on the nipples — it dries out the skin
• If it's raw and painful enough that you can't feed, see a provider — cracked skin can let bacteria in and lead to mastitis

White dot / blister (bleb / milk blister)

A tiny white or yellow spot on the nipple tip is often a blocked opening of a milk duct, where a thin layer of skin has grown over the duct opening. Milk backs up behind it, causing pain during feeding and sometimes a clogged duct further back.

What to do:

• A warm compress before feeds may help soften the skin over the bleb
• Let baby nurse — the sucking may help open it
• After feeding, apply a sterile saline compress to soften the skin
• Do not try to pop it yourself with a needle or pin — this can lead to infection and scarring
• If it doesn't clear in a few days, a lactation consultant or doctor can open it sterilely
• If you develop a fever or redness, see a provider — it may be infected

Burning pain after feeding (possible thrush)

Burning or shooting pain that continues after feeding, often with a red, shiny, or peeling areola, can point to a yeast infection (thrush). The pain is often described as "burning," "stabbing," or "like glass" and can radiate through the breast.

Other signs of thrush:

• Baby has white patches in the mouth that don't wipe away
• Baby is fussy during feeds or pulls off crying
• Baby has a diaper rash that's bright red with satellite spots
• Pain is worse after feeding, not during latch
• Both breasts are affected (thrush often spreads bilaterally)

Treatment: This needs a professional diagnosis. Treatment usually involves both you and baby — an antifungal cream for your nipples and an oral antifungal for baby's mouth — so you don't pass it back and forth. See your OB, pediatrician, or primary care provider.

Pain after cold (Raynaud's / vasospasm)

If the nipple turns white, then blue, then red after feeding or cold exposure, with sharp pain on rewarming, it may be Raynaud's phenomenon — a blood-flow (vasospasm) issue, not an infection. The blood vessels in the nipple spasm in response to cold or stress, cutting off circulation temporarily.

What helps:

• Keep warm before and after feeds — use a heating pad or warm hand on the breast
• Avoid cold drinks and cold rooms right after feeding
• Wear a warm bra or tank top, even indoors
• Don't use ice packs on the nipple if you have Raynaud's — use them on the breast tissue behind the nipple instead
• An IBCLC can confirm and advise; in severe cases, a doctor may prescribe medication to improve blood flow

Pump-related pain

If you're pumping and your nipples hurt, check these three things first:

1. Flange size: The wrong size means your nipple rubs against the tunnel. You should have a little space around the nipple — it shouldn't rub the sides, and too much areola shouldn't be pulled in. Measure your flange size.
2. Suction level: Higher isn't better. Start low and increase only to the level where milk flows comfortably. If your nipples hurt or look bruised after pumping, turn it down.
3. Pump timing: Don't pump for more than 15–20 minutes per session. Longer doesn't mean more milk — it means more trauma.

When a tongue tie is the hidden cause

If you've tried repositioning and the pain persists, baby may have a tongue tie — a tight band of tissue under the tongue that limits movement and prevents a deep latch. Signs include:

• Pain that doesn't improve with positioning changes
• Baby makes a clicking sound while feeding
• Baby can't stick their tongue out past the lower lip
• Baby's tongue looks heart-shaped when lifted
• Poor weight gain or frequent feeding (baby isn't transferring milk well)

A tongue tie release is a simple procedure done by a pediatrician, dentist, or ENT. After release, most moms see immediate improvement in latch comfort. If you suspect a tongue tie, ask your pediatrician or an IBCLC for an evaluation.

Red flags: call your doctor today

• Fever of 101°F (38.3°C) or higher
• A hot, red, hard area on the breast
• Redness spreading, chills, or flu-like symptoms
• A cracked nipple that looks infected (pus, increasing redness, warmth)
• Pain that's getting worse despite trying the above steps
• You can't feed because of pain — you need help to keep milk supply going

Nipple pain is one of the top reasons moms stop breastfeeding earlier than planned. But most causes are fixable, often within a few days. If you're in pain, don't wait — get a latch assessment from an IBCLC. Find one near you or take our nipple pain check to narrow down the cause.
