My 2 year old started a fever last night. At 6 am she vomited and her fever was high. Her fever has spiked to as high as 105, and with Motrin drops down to 100. She only vomited one more time today but she's been keeping down some bread and some fluids. Her fever is now spiking again and she's not due for Motrin for another 45 minutes. I called her doctor earlier and they said not to worry but it's still not getting any better. Should I take her to the er?
