Flu with fever for 6 days on Going is that normal

Miyaz • Wife & mommy to my two babies 💕

So my kids and I have the flu for about a week now but both my April baby and 4 year old have a fever for 6 days on and off and non stop coughing is that normal their symptoms come and go just when I think they’re better boom fever spikes again . I took them to children’s hospital and doctors all saying same shit it’s a virus it has to run its course . Really non stop fever for a week almost has to run it’s coarse
