For acute mastitis, it is important to keep the nipples clean. The nipples should often be washed with soapy warm water, and rinsed with clean water before and after breastfeeding. Patients with inverted nipples should gently extrude the nipple before cleaning it, but should not use alcohol to clean the area, as alcohol can make the skin of the nipple and areola brittle and prone to cracking. It is important to develop good breastfeeding habits, breastfeeding on a regular schedule, and ensuring that all the milk is drawn out each time. If the milk cannot be fully expressed, it should be manually massaged out or extracted using a breast pump. Additionally, do not let the baby sleep with the nipple in their mouth. If there are any nipple injuries or cracks, stop breastfeeding, use a breast pump to extract the milk, and resume breastfeeding only after the wounds have healed.
