When breastfeeding women have milk on one side of the breast and no milk on the other, they can improve by promoting baby sucking, moderate massage or adjusting their diet. 1. baby sucking: it is recommended that when feeding the baby, the side with relatively less milk should be fed first, and the baby should take the whole nipple and areola into the mouth when sucking, as the baby’s strong sucking stimulates the areola and easily stimulates milk secretion, which has a positive effect on speeding up milk excretion. 2. Massage: you can use warm towels to apply to your breasts and massage them gently, or ask a professional lactation therapist to perform lactation treatment, and machine physiotherapy is also effective in promoting milk secretion. In addition, when breastfeeding, you need to pay attention to keep the nipple area clean and hygienic, especially after feeding, you can use water to wipe the nipple area gently. After wiping, you can cover the nipple surface with clean, dry gauze to reduce nipple damage and prevent bacteria from entering the mammary gland through the nipple, which can contaminate the milk in the mammary gland and form mastitis.
