Breastfeeding can reduce milk secretion by reducing the baby’s sucking on the mother’s nipple, reducing the excessive emptying of the mammary glands, and adjusting the diet. 1. Reduce the baby sucking on the mother’s nipple: In the process of breastfeeding, the baby continues to suck on the mother’s nipple, so that the nipple area of the nerve is stimulated, the stimulation is transmitted to the pituitary gland, thus increasing the secretion of lactogen, and then stimulate the breast to secrete milk. Therefore, if you want to reduce the amount of lactation, you have to reduce the baby’s sucking on the mother’s nipple. 2. Reduce the excessive emptying of the mammary glands: During the breastfeeding period, the breasts will adjust the speed of milk discharge according to the degree of swelling of the breasts, the breasts are generally not absolutely empty, the side of the milk discharge lactation, the more the more discharge. Usually, the higher the degree of breast emptying, the more milk will be produced. 3. Adjust the diet: adequate nutritional intake of postpartum breastfeeding mothers is the material basis of milk secretion, you can adjust the diet to reduce the intake of high-fat, high-protein soups (such as fish soup, broth, chicken soup, etc.), can also be reduced to a certain extent to reduce the secretion of milk. Excessive milk during breastfeeding may lead to mastitis or even pus development into breast abscess, if the breast has redness, swelling, fever, pressure pain, etc. must go to the hospital in a timely manner, and follow the doctor’s instructions to deal with the treatment.
