Cold, cough and runny nose in a one-year-old baby is a more typical symptom of a cold, which can also be a symptom of an upper respiratory tract infection. In the early stages of the disease, the main thing is to treat the symptoms, for example, you can take oral ai chang, symptomatic treatment, to relieve the child’s cough, runny nose symptoms. If your child has this condition for more than 3 days, be sure to get a doctor’s hearing. If the child’s phlegm is a little bit more white phlegm, or there is thicker phlegm, you can take medicines to dissolve phlegm, such as Ambroxol oral liquid, or Etanercept oral liquid, which has the effect of dissolving phlegm. If you can add nebulization, the effect will be better. At the same time, observe the child to see if the cough has worsened and if it is deeper. If the cough is heavier, coupled with faster breathing or more labored breathing, be sure to have a doctor listen to the patient to rule out a combined lung infection. This is because initially, it may be an upper respiratory tract infection caused by a cold, which may later worsen into pneumonia. Children with pneumonia must be treated early.
