Most coughs with phlegm are caused by respiratory infections. As babies are too young to spit, they will swallow the phlegm even if it has been coughed up. Once a large amount of phlegm and germs accumulate in the respiratory tract, it will lead to bacterial infection, causing further respiratory infection or even pneumonia. It is recommended that when the baby coughs, pick up the baby and gently pat the baby’s back with an empty palm, up and down, left and right. Patting the back can play the role of broadening the chest and promoting the discharge of phlegm. At the same time to drink more warm boiled water, keep the throat moist, drink more cool boiled water can make the immune secretion is diluted, easy to be coughed up. The use of cough suppressant and expectorant drugs is conducive to the elimination of local inflammation. You can take pediatric phlegm and cough punch, or use medication under the guidance of a physician. You can give your baby to drink Chuanbei soaked pear water, which has the effect of clearing heat and moistening the lungs, relieving cough and resolving phlegm, and tonifying the qi and strengthening the spleen. Usually should pay attention to keep warm, avoid cold.
