Squeeze out a little milk and smear it on the nipple and areola after each lactation to keep the nipple dry, and at the same time let protein in the milk promote the repair of nipple injury.
Don't let the baby suck when the pain in the crack is severe. Suck out the milk with a breast pump in time, or squeeze out the milk by hand to feed the baby, so as to reduce the inflammatory reaction and promote the fracture healing. But don't give up breastfeeding easily, otherwise it will easily reduce milk or cause furuncle and mastitis.
When the nipple is cracked, you can still continue breastfeeding, but you should pay attention to correcting the way your baby sucks. You can't just suck the nipple, you must also let the baby have areola.
When breastfeeding, feed the good breasts first. This is because the hungry baby will exert more force when he first starts to suck milk, and then suck the cracked side after sucking one side, so the sucking force will slow down and relieve the pain. After breastfeeding, a small amount of milk can be applied to the nipple. Milk has antibacterial effect, and rich protein is also beneficial to epidermis repair.
