There are never clear-cut answers. I am a nurse..(not a pediatric) but one of the things I have learned in my career is that each human is truly unique and while there are generalities on how we respond to different illnesses, humans can respond very differently than what it the norm for most. My baby had teething with a temperature over 103. He was normal in every other way - giggly, fun, happy...with a temperature over 103. It was nothing but teething. If it lasts more than 2 days or does not come down with Tylenol or Motrin, definitely see your doctor. Febrile seizures are not uncommon so keep the temps under control.
