Frequently Asked Questions
What temperature counts as a fever?
Rectal (most accurate for young children): 100.4°F / 38°C or higher. Oral: 100°F / 37.8°C or higher. For babies under 3 months, always use a rectal thermometer.
Should I wake my child to give medicine?
Usually no. Sleep is restorative. The exception: wake them if the fever is over 103°F or they seem unusually difficult to rouse.
Can I alternate Tylenol and Advil?
Yes, but be careful. You can alternate every 3 hours. The risk is double-dosing, so write down every dose with the exact time.
How long do fevers normally last?
Most viral fevers last 3–5 days. See a doctor if it lasts beyond 5 days, or disappears for 24+ hours and returns.
Should I try to 'break' the fever?
Fever itself isn't dangerous — it's your child's immune system fighting infection. Treat the child, not the number.
