Babies with a fever of 38.5 degrees can be given physical cooling with a small amount of water. Physical cooling is to continuously wipe the forehead, neck and other vascular areas with warm water, and pay attention to diligent temperature measurement. If your baby’s temperature is over 38.5 degrees, you can take oral ibuprofen to reduce fever. And pay attention to whether your child has a stuffy nose, runny nose and other symptoms of respiratory tract infection. If there is, you can take oral antiviral drugs such as pediatric aminoglutethimide pellets to treat the symptoms. If your child has repeated fever, you need to go to the hospital for routine blood tests and, if necessary, intravenous fluids for treatment. Because the child is relatively young, he should be closely monitored for changes in his condition.
