Thank you for your query.
Fever means temperature>100F.
If your child does not have fever then the child should not receive crocin
or any antibiotic.
Antibiotics should be prescribed after doing blood tests.
Sleep is a way by which the body takes rest and recovers after a viral fever
.This is absolutely normal.Give him lots of rest and plenty of fluids.
Hope this answers your query.
If you have any other queries kindly direct them to me.
Wishing a speedy recovery.
Have a nice day.
