It is not recommended to eat the breast milk of a mother with mastitis, as it may contain bacteria or viruses, which may cause corresponding infections, gastrointestinal symptoms or fever and other symptoms of infection and poisoning, and then breastfeeding should be replaced by infant formula, and breastfeeding should be resumed after the mother has recovered from the disease. It is also important to pay special attention to observe whether there are corresponding clinical symptoms, because mothers with infections are usually in close contact with their children and may transmit viruses or bacteria to their children through close contact or airborne transmission, so it is possible to have infections, and it is important to closely observe the specific situation and take intervention and treatment measures in a timely manner.
