Breastfeeding cracked nipples can be helped to heal by general treatment and medication. 1. General treatment: If a breastfeeding woman’s cracked nipple is mild, she can apply a small amount of milk to the nipple and areola. Milk has an antibacterial effect and can also help the skin recover. Keeping the nipple clean and moist promotes healing. Women can also apply hot compresses to the nipple and areola, but hot compresses can only relieve pain and have no antibacterial effect. 2. Medication: If the nipple cracking of breastfeeding women is more serious, they need to use medication such as lanolin ointment under the guidance of a doctor, which can reduce the loss of moisture on the skin surface and resist external stimuli. If a secondary bacterial infection occurs, it can be treated with medications such as erythromycin ointment and mupirocin ointment. If breastfeeding nipple cracking is more serious, it is recommended to go to the breast surgery department of the hospital, and the use of medication needs to be under the guidance of a doctor.
