When a baby has a cold, it indicates that the baby has an acute upper respiratory infection. Over 90% of colds are caused by viral infections, and 10% are caused by bacterial infections. When a child catches a cold, in addition to administering medication, nursing care is very important. First, the child should be allowed to rest, sleep more, drink plenty of plain water, and avoid vigorous activities. It is important to monitor the child's temperature and promptly manage any symptoms if the child develops a fever. Additionally, ensure that the child's diet is light and easy to digest; it's better to drink more soups and avoid fatty meats or sweets. Also, under the guidance of a doctor, administer symptomatic medications to the child, and always follow the instructions carefully when using medications to avoid taking too much or too little, as either can be inappropriate.
