If a 2-month-old child has a fever, the following measures can be used to improve it: First, it is to physically cool the child. If a 2-month-old child has a very low fever that does not exceed 38.5°C under the axilla, it is only necessary to physically cool the child and to drink more warm water as appropriate. This is because physical cooling can effectively lower the child’s temperature, especially if the child’s body temperature is not very high. Drinking more warm water can replenish the excessive water consumption caused by fever, and after replenishing water, it is also beneficial for the child’s fever to subside. Secondly, it is important to apply antipyretic medication for children in a timely manner. If a child’s body temperature exceeds 38.5°C in the axilla, the child will often be uncomfortable and can be given antipyretic medication, such as acetaminophen. Finally, children should be treated promptly for the cause of the illness. If the fever is caused by a bacterial infection, the child can be treated with cephalosporins to combat the infection.
