The causes of white spots or white blisters on nipples during breastfeeding are milk stagnation and wrong breastfeeding posture. It is recommended to empty the breasts in time and adjust the breastfeeding posture. 1. Use hand milking: use hand milking to empty breast milk as much as possible, reduce milk stagnation and avoid aggravating nipple white spots or white blisters. 2. Let the baby suck more: the negative pressure formed in the baby’s mouth when he eats milk is very big, if it is due to the blocked milk holes, let the baby suck more, so that the milk holes can be restored to smooth. 3. Adjust the breastfeeding posture: including the mother’s breastfeeding posture and the baby’s breastfeeding posture need to be adjusted, the mother can try different angles of the posture, which can make the white spots or white bubbles on the nipple break through more quickly. When white bubbles appear on the nipple blocking milk during breastfeeding, don’t pick it by yourself, it is easy to cause nipple skin breakage or infection, it is recommended to go to the hospital breast specialist in time.
