The phenomenon of back milk in one breast is mainly caused by improper breastfeeding and is related to long-term breastfeeding with one breast, which can be remedied in the following ways: 1. You can also apply hot compresses to your breasts to promote local blood circulation and milk secretion; 3. You should pay attention to a balanced diet with the intake of fat, protein, vitamins, calcium and iron, such as lean meat, chicken, fish and pork ribs, soybeans, eggs and milk, and you can drink more chicken soup, fish soup and pig’s feet soup to promote milk secretion. In addition, it is recommended that each breastfeeding should alternate between both breasts to allow the milk to empty. If the amount of milk from one breast is sufficient to meet the baby’s needs, you can take turns feeding one breast at a time and suck out the milk from the other side with a breast pump. During breastfeeding, pay attention to getting enough sleep, exercising properly, keeping a regular life, trying not to stay up late, and making your mood happy.
