Five-month-old baby with runny nose and nasal congestion can be given appropriate pediatric cold medicine, such as pediatric cold granules, for 3-5 days and observed if the child does not have fever, is in good spirits, and the runny nose and nasal congestion seriously affect the child’s milk intake and sleep. Also spray the nasal passages with physiological sea saline spray to relieve nasal congestion. Because this kind of children’s cold is usually more than 90% viral, it is a self-limiting process. Usually no special intervention is needed, but mainly symptomatic treatment is sufficient. Give your child a proper amount of water, especially when it is hot. If the child’s nose turns yellow, it usually indicates a co-infection with bacteria and the addition of antibiotics is recommended. If the child develops a fever with a temperature repeatedly exceeding 38.5°C and the duration of the illness is more than 3 days, it is recommended to visit the pediatrician for an interview and blood tests are required.
