10 months infant persistent fever

Pls bring your baby to see a doctor. I recently experienced the same - baby had fever for 4 days. Despite taking paracetamol every 6 hours, the fever just kept coming back at 38.5 deg and above. On day 4 of fever, I brought baby to see a doc and they did blood test. Turned out that he is having bacteria infection of the lungs, hence breathing heavily - as pointed out by his doc. Was prescribed antibiotics, other meds and asked to use nebuliser to clear his lung infection. Aside from fever, my baby had bad cough, runny nose. But he still appeared active and hyper, despite the heavy breathing. Really wouldn’t have known something more serious was actually happening to him if we didn’t bring him to see a doctor. Please do not take fever lightly. Especially if it’s been ongoing for some time, better find out what’s wrong.
