Infants with cold and cough will generally heal themselves in a few days, depending on the severity of the disease and the child’s physical condition, and should be analyzed on a case-by-case basis. The symptoms of nasal congestion and coughing in infants with colds are considered to be respiratory tract infections. If the condition is mild, it can generally heal itself in about 7 days. However, due to the child’s young age, relatively weak resistance and the fact that the temperature center is not yet well developed, pneumonia cannot be excluded and active treatment should be given to avoid aggravation of the symptoms. If the symptoms persist for a longer period of time, it is recommended to promptly visit the pediatric internal medicine department of a regular hospital, and if necessary, routine blood and chest X-ray examinations should be conducted to clarify the diagnosis and then carry out targeted treatment. In addition, if the child’s nasal congestion is severe, parents can give the baby a hot compress on the root of the nose or fontanelle area to relieve the symptoms. It is also important to give the child more warm water to promote metabolism.
