Hi dr. My 18 months old (10.2 kg) having fever from last Wednesday night with runny nose and cough. Gave her infant Tylenol for first 2 days but fever was keep coming back and her cough sounding very congested. So I took her to the dr. She prescribed antibiotics ( azithromycin) last nite gave her the 2nd dose of antibiotics and givin tyle mil every 6 hours but still no difference, fever is keep coming back. She hasn't eaten anything solid for last 3 days, completely on my breast milk. I am worried if there is anything I should be concerned about plz help
