28 mnth old r ear infection, cough, no fever. prescribed orciprenaline & cefprozil if infect'n persists (>36 hrs. ) concerned about giving antibiotic?

Confusing treatment: Some research centers suggest we hold abx for a few days because a fraction of ear infections are viral and self heal. I think I can tell the difference in viral/bacterial infections and treat or not based on my exam.I can see the confusion, but in my world the kid would get the abx and nothing else, the add on does little if anything.
