Fever Follow Up Guide: What Parents Need to Know

Understanding Fevers

  • Definition: Core temperature (rectal, oral, or temporal) of 100.4°F/38°C or higher
  • Purpose: Your child's immune system fighting an infection
  • Common symptoms: Chills, headache, body aches, fatigue

A fever itself is not an illness—it's the body's natural way of fighting infections.

When to Let a Fever Run Its Course

A fever is often a good sign that your child's body is working to fight infection. You can let a fever run its course when:
  • Your child is still drinking fluids
  • Your child is responsive and can be consoled
  • Your child seems uncomfortable but not in severe distress
  • Temperature responds somewhat to fever reducers

How to Safely Treat a Fever at Home

🏠 Home Remedies
  • Hydration: Offer breastmilk, formula, water, or electrolyte solutions frequently
  • Clothing: Light layers, avoid over-bundling
  • Environment: Comfortable room temperature
  • Bathing: Lukewarm sponge baths only (avoid cold baths)
  • Rest: Allow adequate sleep  
  • Appetite: Don't worry if appetite decreases
💊 Medication (Use when fever is causing discomfort, poor feeding, or sleep disturbance)
  • Acetaminophen (Tylenol): 10-15 mg/kg every 4-6 hours (max 5 doses/day)
    • Safe for babies 3+ months
  • Ibuprofen (Motrin/Advil): 5-10 mg/kg every 6-8 hours
    • Safe for babies 6+ months
  • ⚠️ Never give aspirin to children (risk of Reye's syndrome, a rare but serious condition that can cause brain and liver damage)

When to Go Straight to the ER

  • Flaring nostrils
  • Pulling in of the ribs (retractions)
  • Grunting sounds

  • No urination for 8+ hours

Trust Your Parental Instincts

Don't panic over the number on the thermometer (if over 3 months). A child's behavior is a better indicator of how sick they are. If they're drinking, playing, and alert between fevers, that's reassuring.
