A. Fever is a response of the body to any kind of infection or any inflammatory process in body so you can give paracetamol in a dose of 15 mg/kg/dorse as the first line treatment also this dose can be again repeated after every 5 to 6 hours if fever is repeating. and you can alsog do cold sponging of the body if required
