Fever in children is a relatively common problem. If the fever does not exceed 38 degrees, you can observe the child’s condition and do not recommend the use of physical cooling methods. If it exceeds 38 degrees, you can decide when to give fever-reducing medication as an adjunct to treatment based on the child’s temperature and the specific situation. Generally if the child’s temperature is not particularly high, for example, not more than 38.5 degrees, but the child has obvious discomfort, you can consider giving the child antipyretic drugs, such as ibuprofen or acetaminophen, etc., but if the child’s temperature is relatively high, for example, more than 38.5 degrees, but the child’s mental response is good, no obvious discomfort performance, but also can wait, do not use drugs, pay attention to give the baby to drink more warm water, do not cover too much clothing. Physical cooling method used to be a very common method to reduce fever in clinical and life, mainly including warm water wipe, alcohol wipe, cold towel on the head, or ice bag cold compress, etc., but now the above methods have been clearly not recommended because they may cause obvious discomfort to the child, so when the child has a fever, try not to use the above physical cooling methods. Babies generally don’t have any appetite when they have a fever, so do some food that your baby likes to eat, and light food should be the main focus. Some snacks and drinks should not be eaten anymore, which may affect the recovery of the disease. Fever in children is generally a stage that is bound to pass, so do not worry too much. The timely examination and treatment, generally there will not be any big problem, adhere to the general fever two or three days will be better.
