If you have a slight cough, you need to find out the cause of the cough, and if there is a serious infection, you cannot breastfeed your baby. When a mother has a mild cough, she should first observe the symptoms, and if she gradually recovers, she can breastfeed her baby, but she should clean her hands and wear a mask before breastfeeding, so as to avoid coughing up saliva and spraying it on her baby, which may cause her baby to get infected and sick. If the maternal cough is severe and requires medication or fever has occurred, it is not recommended to continue breastfeeding, and it is necessary to clarify the cause of the cough, such as colds, pneumonia, upper respiratory tract infections, whether or not there are viruses, bacteria, mycoplasma, chlamydia and other pathogens, and then treat them positively and breastfeed after recovery.
