When a 5-month-old baby has a fever of 38°C, you can first use physical cooling methods for the child, because the child’s body temperature does not exceed 38.5°C, you can temporarily do not take antipyretic and analgesic drugs first. You can use diluted white wine or alcohol to wipe the child’s skin all over the body, especially in the armpits, groin, neck, palms and feet where the blood vessels are rich, and the wiping time can be slightly longer. If your child has a fever with a rash or is taking cephalosporin antibiotics, it is best not to use alcohol or white wine, but to use a warm water bath. You can also put a fever-reducing patch on your child’s forehead or neck to relieve the discomfort of a fever, although the fever-reducing effect is relatively weak.
