Thank you for your query on Healthcare Magic,
Your child seems to have a Viral fever
You can give Tylenol
every 6 th hourly and as there is high grade fever, you do tepid sponging the whole body with lukewarm water.
Provide adequate rest.
Try to give plenty of oral fluids, juices, and soft diet
to maintain hydration and nutrition.
Consult your Pediatrician
for the examination to look for the cause of fever and to treat accordingly.
Hope I have answered your query.
