If the baby is still sleeping when the fever is 39℃, it is recommended to use physical cooling methods to reduce the fever. You can put a fever reducing patch on the child’s forehead or use a warm towel to wipe the child’s whole body skin, especially in the armpits, groin, neck and other places where blood vessels are rich, and the wipe should be slightly longer, which is helpful to reduce the fever. If the temperature can come down and if it can come down to below 38.5℃, it is fine to keep giving physical cooling to the child. If the temperature does not come down, the child needs to be woken up and given oral antipyretics for treatment. It is recommended that the child be given oral ibuprofen suspension or acetaminophen suspension for treatment. In addition, you need to give your child more water. After taking antipyretic drugs, there is often a lot of sweating, and the child will experience dehydration, so it is important to give your child some plain water. When the fever is high for water consumption, you also need to drink more water, preferably some light salt water.
