"What temperature is considered a fever?"
Rectal: 100.4°F (38°C) or higher. Oral: 100°F (37.8°C) or higher. Ear: 100.4°F (38°C) or higher. Armpit temperatures are less reliable but 99°F (37.2°C) or higher may indicate fever.
When your child has a fever, it can be scary. This guide helps you assess severity and respond appropriately.
If your child has a fever with difficulty breathing, severe lethargy, or is under 3 months old with any fever, seek emergency care immediately.
Say exactly:
""I'm calling about my [age] child who has a high fever of [temperature]. They are showing these symptoms: [list symptoms like difficulty breathing, extreme lethargy, rash]. The fever started [time] ago. We are at [your exact location/address].""
Say exactly:
""My child's fever is [temperature] and started [time] ago. I've given them [medication and dosage] at [time]. They are also showing: [list all symptoms]. Their normal temperature is usually [normal temp]. They [have/don't have] any medical conditions.""
Monitor your child for these symptoms:
Rectal: 100.4°F (38°C) or higher. Oral: 100°F (37.8°C) or higher. Ear: 100.4°F (38°C) or higher. Armpit temperatures are less reliable but 99°F (37.2°C) or higher may indicate fever.
Generally no. If they're sleeping comfortably, let them rest. Only wake them if the fever is very high (over 103°F/39.4°C) or if they seem uncomfortable even while sleeping.
Yes, but only under specific guidance. You can alternate them every 3 hours, but it's easy to overdose. Write down exact times and doses. When in doubt, stick to one medication.
No, never use ice baths, cold water, or alcohol rubs. These can cause shivering (which raises body temperature) or dangerous temperature drops. Lukewarm baths are okay if your child enjoys them.
Most viral fevers last 3-5 days. The pattern often includes higher fevers in late afternoon/evening. If fever persists beyond 5 days or returns after being gone 24+ hours, see a doctor.
"I learned to trust my gut over the thermometer. My daughter had a "low" fever but was acting really sick - turned out to be strep."

"Keep a fever log on your phone. Doctors always ask when it started and what you've given. Having exact times saved us multiple ER visits."
