Toddler with fever no other symptoms
I just went through this last week, spent the entire week frantically googling answers, so here's what I have to share.
If it's just a fever, odds are it's just a virus-based illness. Keep this list in mind:
Normal temperature – 97 to 99 degrees (36 to 37.2 Celcius).
Low-grade fever – 99 to 100.9 degrees (37.3 to 38.3 Celcius).
Common fever – 101 to 103.5 degrees (38.4 to 39.7 Celcius).
High fever – any fever over 103.6 degrees (39.8 Celcius).
And note that low-grade to common fevers are not dangerous in and of themselves--they are signs that your little one's body is fighting an illness. Should you treat it? Not always--if your child appears to be suffering negatively from the fever, treat it. If not, you can let it go untreated. To quote Dr. Sears, "Treat the child, not the fever."
I did not use a cooling bath to treat my daughter's fever. I have read that lukewarm baths can be used, but they should be used in addition to OTC medication such as acetaminophen or ibuprofen.
