Thanks for your query.
Since your child is having fever
which according to your pediatrician
is viral in nature,she needs symptomatic treatment.
Record temperature 6 hourly and give acetaminophen
as per dosage 15mg/kg till fever is 100F.
sponging to be done with tepid water not cold
water.when temperature is above 102F.
Give plenty of fluids,fruit juices ,vegetable soup and soft bland diet so as to maintain hydration and nutrition.
In case symptoms persist get her re evaluated by pediatrician.
Wishing your child good health.
