Why does breastfeeding hurt?
Positioning and attachment are common reasons for breast or nipple pain, but there can be other causes. Ask for help if the pain continues.
The short answer
Positioning and attachment are common causes of breast or nipple pain during feeding. Pain can also be linked to engorgement, a blocked duct or infection, so ask a midwife, health visitor or doctor to help identify the cause.
Pain can have more than one cause
The NHS says a baby's position and attachment are common causes of nipple or breast pain. Latching is a skill that a parent and baby learn together. Small adjustments may make feeding more comfortable, but an article can’t check a latch from a description.
The NHS also describes pain with engorgement, blocked ducts and some infections. These can feel different and may need different support. Ongoing pain is a good reason to contact your midwife, health visitor or breastfeeding specialist.
Ask someone to observe a feed
A midwife, health visitor or breastfeeding specialist can watch how your baby attaches and feeds, then help you find a comfortable position. The NHS advises getting help with breastfeeding problems rather than trying to solve persistent pain from a general checklist.
If you’re also concerned that your baby isn’t feeding well, tell the professional about changes in feeding, wet nappies and weight checks. Those details help them consider the wider picture.
Know when to contact your care team
Contact your care team if pain doesn’t go away, if your breast or nipple changes, or if you feel unwell. A hot, swollen or painful area with flu like symptoms can need prompt advice. NHS guidance says to contact a GP or NHS 111 if symptoms get worse or aren’t improving within 12 to 24 hours.
