Women should not express milk during breastfeeding, because mastitis and breast lumps can easily occur during the process of milking, which can lead to breast infection. Women should not eat greasy food during breastfeeding, and can take high doses of vitamin B6 tablets, fried malt water, and apply mannitol to the breasts for comprehensive treatment. Breast swelling will occur in 3-4 days, and then the swelling will be relieved automatically and gradually. When a woman cannot breastfeed for special reasons after giving birth, or when the baby needs to be weaned, there are methods that can be used to get the milk back. In addition, women should pay attention to the cleanliness and hygiene of their breasts during the milk return period, and also pay attention to avoid squeezing and bumping the breasts, and wear loose underwear to avoid causing damage to the breasts.
