My 3 year old DS got poorly last sunday high temp last weekend and not feeling himself so took him to the GP they said viral infection and then coughing started back to GP five days later then diagnosed with chest infection given antibiotics (amoxicillin) now we are on 4th day of antibiotics we are on the mend no temperature however slight coughing here and there but now during recovery hes been overly tired NOT MUCH OF A appetite drinking ok but more importantly really tired. I dont know whether that's part of recovery but I am really paranoid. Is there anything anyone can maybe advise?
