Hi there, I can totally understand your concerns. First of all, I need to whether she has any cough or cold or runny nose or ear ache?
If its only fever, then have you measured it? Just to understand the grade of fever.
Next Steps
I would advice you give her calpol syrup if you already have it and the doctor have told you to give it to her anytime in the near past as per her weight. If not, then you will require to consult online with the questions I have asked above and we will try to take care of it.
Secondly measure temperature and if its equal to more than 102 or if the fever is not subsiding despite giving medications then do NORMAL WATER (not cold water not hot water) sponging of the whole body.
