What causes nipple soreness in breastfeeding?

The most common cause of nipple soreness in breastfeeding is poor latch — when the baby is not taking enough breast tissue into the mouth, the nipple is subject to friction and compression causing pain. Other causes include thrush (nipple and breast candida infection), tongue-tie in the baby (restricting effective latch), skin conditions (eczema, contact dermatitis), and overenthusiastic pumping.

What helps with sore nipples?

Ensuring an effective, deep latch is the most important intervention — a properly latched baby should not cause nipple pain. Expressing a small amount of colostrum or breast milk and applying it to the nipple after feeding promotes healing. Purified lanolin or hydrogel pads provide comfort. Air-drying after feeds and avoiding wet or synthetic fabrics helps. If pain is severe, a lactation consultant assessment is important to identify the cause.

How do I know if nipple soreness is thrush?

Nipple thrush typically presents as burning or shooting pain during and after feeding (rather than only during the latch), with pink or flaky nipple skin and sometimes white patches in the baby's mouth. Both mother and baby usually require simultaneous treatment. A GP can confirm the diagnosis and prescribe appropriate antifungal treatment.

When should I seek professional help for nipple soreness?

Seek support if pain is severe enough to make you consider stopping breastfeeding, if nipples are cracked, bleeding, or not healing, if you have shooting pain or deep breast pain suggesting thrush, or if your baby seems to be struggling to feed effectively. A certified lactation consultant (IBCLC) is the most appropriate specialist.
