It is generally not recommended to bathe your baby with a fever of 39℃. Because the temperature and ventilation in the house are not suitable for bathing your baby, it may cause the wind to catch a cold and may cause other infections, etc. When your baby has a fever, you can use warm water to wipe the forehead, the two armpits, the body, the thighs and so on with a warm towel. In addition, babies with fever up to 39°C need to take antipyretic medication. For children, it is necessary to find out the cause of the fever to 39℃, such as bacterial infection or viral infection, and to apply antibacterial or antiviral drugs to give targeted treatment, so do not bathe your baby at this time.
