For 10-month-old babies with cough and phlegm symptoms, you can take aminoglutethimide oral solution to treat the symptoms of cough and phlegm. If the symptoms of coughing and phlegm are more pronounced and even cause difficulty in sleeping, coughing and phlegm can be relieved by nebulization. Parents should also pat the affected child’s back more often, which can promote the smooth discharge of phlegm. At this time, treatment should also be given to the primary cause. If the trachea or bronchitis is caused by bacterial infection, cefaclor or cefixime granules can be taken for anti-inflammatory treatment. If it is a mycoplasma infection or the child is allergic to cephalosporins, you can take roxithromycin or azithromycin pellets for treatment. Parents should pay attention to keep a certain amount of humidity as well as ventilation in the room to facilitate the discharge of sputum from the affected child, and it is generally recommended that the humidity should be around 50%-60%.
