A Parent's Guide to Childhood Fever

Fever is the body's natural response to infection — it's actually a sign that the immune system is working. But knowing when to worry and when to wait is one of the most stressful parts of parenting.

What Is a Fever?

A fever is generally defined as a temperature of 100.4°F (38°C) or higher. Normal body temperature varies slightly by person and time of day.

When to Call the Doctor Immediately

• Any fever in a baby under 3 months old
• Fever above 104°F (40°C) in any child
• Fever lasting more than 5 days
• Child is inconsolably crying, difficult to wake, or has a stiff neck
• Rash appears with the fever
• Signs of dehydration (no tears, dry mouth, no urination in 8+ hours)
• Difficulty breathing

Safe Home Management

For children over 3 months with mild to moderate fever:

1. Dress lightly — heavy clothing traps heat
2. Encourage fluids — water, diluted juice, or oral rehydration solutions
3. Use fever reducers appropriately — acetaminophen (Tylenol) for infants 2+ months; ibuprofen (Motrin/Advil) for children 6+ months. Never give aspirin to children.
4. Lukewarm sponge bath if the child is uncomfortable (not cold water)

What NOT to Do

• Do not use cold water or ice baths
• Do not alternate medications without doctor guidance
• Do not give aspirin to anyone under 18 (risk of Reye's syndrome)
