14 month DD had pneumonia in December so I'm ultra conscious of when she gets ill and she's had a cough pretty much ever since. She's had a temperature of 38.5-40 for 2 days now and the dr can't find anything wrong (same thing happened last time). Calpol and calprufen are doing nothing. Is this normal in babies or should I go back to the hospital and ask for blood tests again in your opinion? So worried.
