Children's colds are mostly viral infections and are self-limiting, which means they can resolve on their own. Therefore, no special treatment is needed in the early stages of a child's cold, but it is important for the child to drink plenty of water and get plenty of rest. If an adult at home has a cold, avoid contact with the child and ensure good ventilation; windows should be opened daily for air circulation. Additionally, feed the child light, easily digestible foods. If the child experiences significant nasal congestion or runny nose causing discomfort, child-specific cold granules or physiological saline nasal wash can be used to relieve the symptoms of the cold. (Please use medications under the guidance of a doctor.)
