So my daughter is going on day 3 now with a fever. The highest its been was 101.7. I've been giving her motrin to help and it will for a few hours then goes back up to 101. Plus today she had diarrhea but that's the only time so far. I'm not sure what's causing it. Her doctor said to take her to the er if it reaches 102. She's seem more tired than usual and today has acted super thirsty.

Really stuck on what's causing it and why it hasn't gone down in 3 going on 4 days.. Any tips?
