Most coughs are caused by upper respiratory tract infections due to bacterial or viral invasion, aggravated and developed inflammation of the lungs causing coughing, which is mainly transmitted through the respiratory tract, not through breast milk. Windows can be opened to allow air convection and can reduce the rate of mutual transmission. When breastfeeding your child, it is best to wear a mask and wash your hands frequently to avoid spreading the infection to your child. If the cough is caused by wind-cold cold, it can be treated with San’ao Tang (三拗汤) combined with Zi Couch San (止嗽散), which is effective in dispersing wind and dispersing cold, and promoting the lungs to stop coughing.
