Here is the thing nobody says clearly enough: breastfeeding is not supposed to hurt.
Some tenderness in the first week is common while your nipples adjust. But pain that makes you dread the next feed, cracks that bleed, or a stabbing sensation right through the feed are all signals that something is fixable — not things to endure until they pass.
Most of it comes down to one thing.
Why does breastfeeding hurt?
The most common cause by far is a shallow latch. If your baby takes only the nipple into their mouth instead of a good mouthful of the areola underneath, the nipple gets compressed against the hard palate and pinched with every suck. That causes pain during the feed, cracks over days, and often poor milk transfer as well.
Signs of a shallow latch: pain that continues through the whole feed rather than easing after the first few seconds, a nipple that comes out flattened, creased or wedge-shaped, clicking or smacking sounds, and a baby who feeds for very long stretches and still seems unsatisfied.
Signs of a good latch: a wide-open mouth, more areola visible above the baby's top lip than below the bottom, lips flanged outward, chin pressed into the breast, rhythmic sucking with visible swallowing, and comfort after the initial few seconds.
How do I fix the latch?
Bring the baby to the breast, not the breast to the baby. That single adjustment solves a lot of it.
-
Hold your baby chest-to-chest with you, ear, shoulder and hip in a line, nose level with your nipple
-
Wait for a wide-open mouth — brushing the nipple down across the upper lip usually prompts it
-
Bring them on quickly, aiming your nipple towards the roof of their mouth so the chin lands first
-
Support your own back and arms with pillows, so you aren't hunching towards the baby
If it still hurts, break the suction gently with a clean finger in the corner of their mouth and start again. Repositioning three times is better than one painful feed.
Ask for help early. A lactation consultant or an experienced nurse watching one full feed will spot in two minutes what an article cannot. This is the single highest-value thing in this post.
How do I treat cracked and sore nipples?
Fix the latch first, because otherwise you're treating an injury that's being re-inflicted several times a day.
Then:
-
Express a few drops of your own milk and let it dry on the nipple after feeds
-
Apply a lanolin or purified-lanolin nipple cream — it doesn't need washing off before feeding
-
Let nipples air-dry after feeds; change damp breast pads promptly
-
Start feeds on the less sore side, when the baby sucks most vigorously
-
Avoid soap on the nipples; plain water is enough
If a crack is deep or bleeding, feeding is usually still safe — a small amount of blood swallowed doesn't harm the baby. But it's a strong signal to have the latch assessed properly.
Persistent burning or shooting pain after feeds, sometimes with shiny or flaky nipples, can be thrush, which needs treatment for both you and the baby together. It won't clear if only one of you is treated.
What is mastitis and how do I know I have it?
Mastitis is inflammation of breast tissue, often with infection. It usually starts as a blocked duct — a tender lump in one breast — and progresses to a red, hot, painful wedge-shaped area, along with fever, chills and a flu-like ache all over.
Two features distinguish it from ordinary engorgement: it affects one breast in one area rather than both breasts evenly, and it makes you feel systemically unwell.
What to do:
-
Keep feeding or expressing from that breast. This is counterintuitive and it is the most important step. Milk needs to keep moving. Stopping makes it worse.
-
Feed frequently, starting on the affected side
-
Warm compress before feeds, cold compress after for comfort
-
Rest, fluids, and paracetamol
-
See a doctor if you have fever, or if it hasn't improved in 12–24 hours. Mastitis often needs antibiotics, and untreated mastitis can develop into a breast abscess, which is a much bigger problem requiring drainage.
Most breastfeeding-safe antibiotics let you continue feeding throughout, and you should. Tell your doctor you're breastfeeding so they prescribe accordingly.
When should I see a doctor?
Get medical help if you have fever with breast pain, a red hot area that isn't improving, a lump that doesn't soften after feeding, a deep crack or bleeding that isn't healing, burning pain that persists after feeds, or if your baby isn't gaining weight or having enough wet nappies.
That last one matters. Pain plus poor weight gain usually means milk isn't transferring well, and both problems have the same root cause and the same fix.
Quick answers
How long should tenderness last? Mild tenderness in the first week is common. Pain beyond that, or pain severe enough to dread feeds, needs assessing rather than waiting out.
Can I use a nipple shield? They can help in specific situations — flat nipples, a very sore crack, a premature baby learning to latch. They can also mask a latch problem and reduce milk transfer. Best used with guidance rather than as a first solution.
Is it normal for one breast to make more milk? Yes, very common, and nothing to correct.
Should I stop feeding from a breast with mastitis? No. Continuing to empty that breast is part of the treatment.
Can I take painkillers while breastfeeding? Paracetamol is generally considered safe while breastfeeding. Check anything else with your doctor before taking it.
I'm exhausted and considering stopping. Is that wrong? No. Breastfeeding matters, and so does your wellbeing. Get the pain assessed first — a lot of women who wanted to stop were actually dealing with a fixable latch problem. But a fed baby and a mother who is coping is the goal, and formula is not a failure.
