How does five-month-old baby have a fever?

When your baby has a fever, you can use warm water to wipe your child's forehead, neck, armpit, groin, palm, arm and other parts to promote the lowering of body temperature. You also need to let your child drink more warm water to appropriately lower the temperature of the child's surrounding environment to promote the lowering of body temperature. Avoid wrapping too much clothing for your child.
