In infants with pneumonia, because of the short respiratory tract, the cough reflex is poor and the secretions from the lungs are not completely discharged, so it is more common for the baby to keep spitting bubbles in the mouth. This is accompanied by a lack of energy, shortness of breath, choking or not eating milk, and in some cases, a high fever, which is dangerous. In the case of pneumonia, the child should be hospitalized for 1-2 weeks for observation and treatment until the baby’s symptoms disappear and the test results are completely normal before the child is discharged. Depending on the type of infection, the infant should be treated with antibiotics or antiviral medication. In addition, if the cough and phlegm are severe, it is best to use cough and expectorant medications, such as aminoglutethimide oral solution.
