Thanks for the query
Most of infections in this age group are due to viruses causing fever
. Antibiotics have no role in viral infection and 100 F is mild grade temperature. So continue giving paracetamol
syr, also do tepid sponging to control fever and give water to maintain proper hydration.
Observe if there is high grade of fever, lethargy
,decrease oral intake, any respiratory distress
. If you notice any of these consult your doctor immediately.
I hope this answers your query well
