Pediatric colds and coughs with sputum suggest the presence of secretions in the pediatric airways. And the increase of secretions is often caused by factors such as viral, bacterial or mycoplasma infections. According to different pathogens, antibacterial, antiviral, anti-mycoplasma and cough and sputum medications should be selected for symptomatic treatment and supplemented with nebulization therapy. At the same time, pay attention to drinking more water and eating lightly during cold and cough. Avoid spicy, stimulating, cool and overly sweet foods. If the cold is severe and the sputum is sticky, leading to breathing difficulties and wheezing, you should go to the hospital for further consultation and treatment in time.
