Any fever under 100 does not require a doctors visit until 7 to 10 days if it is the only symptom or only cold like symptoms accompany it . If it was something serious there would be a fever of more than 100. Fevers are not a bad thing. It is the body's way of taking care of itself. If your toddler is pulling on their ears, having trouble breathing, or refusing liquids you should take them to the doctor as soon as possible.
