Breast examinations during pregnancy can detect breast dysplasia and nipple depressions at an early stage so that they can be corrected in time to allow the newborn baby to be breastfed through normal means soon after delivery. The main maternal factors affecting breastfeeding are breast dysplasia (e.g. small nipples) and nipple depression, which can be corrected by manipulation after the 6th month of pregnancy. The specific methods are: (1) for small nipples, the nipples can be massaged 2 to 3 times a day for 10 to 15 minutes each time until full term to promote nipple development by increasing local blood circulation. Correction of the initial period to 5 to 10 minutes each time is appropriate, and then gradually increase the massage time. If there is obvious pain or discomfort in the abdomen, massage should be stopped in time, the occurrence of this phenomenon may be related to the massage stimulation triggered by uterine contractions. In order to avoid miscarriage or premature birth, in the next and subsequent massage to pay attention to the technique, the duration should also be relatively short. (2) for the nipple sunken, the nipple as the center, repeatedly from the inside out to do up and down, left and right pulling action, so that the nipple natural protrusion, and then pinch the nipple neck to pull back and forth, so that the nipple convex, 2 to 3 times a day, 10-15 minutes each time, generally after 1 to 3 months of correction can be cured. When doing the above treatment, attention should also be paid to cleaning the hands of the massager and the breasts of the pregnant woman being treated, and gentle techniques should be used to avoid nipple infection and injury.
