For an 8-month-old baby with a cold and cough, the key is to find the cause of the cough. Violent and frequent coughs are very harmful to the body. For violent and dry coughs, cough medicines, such as Etanercept syrup, can be used for a short time to help stop the cough. For children with coughing, thick and sticky phlegm that cannot be easily coughed out, cough and phlegm-relieving medications should be used, such as expectorant spirit, monkey jujube san and compound fresh bamboo liquid are very good. At the same time, pay attention to ensuring that the child has sufficient water intake to dilute the phlegm and help it to be expelled, pay attention to the air humidity and pay attention to opening windows for ventilation. For cough with obvious signs of inflammation, such as fever, yellow, sticky sputum and increased white blood cells, antibiotics such as cefaclor, amoxicillin or roxithromycin can be added if there is no drug allergy.
