Fever

What is a fever?

A fever means your child’s body temperature is higher than normal. For children under 5, a fever is a temperature of 100.4°F (38°C) or higher. Fever is the body’s way of fighting infection — it is usually not dangerous on its own, but it tells you something is going on that needs watching.

What to watch for at home

• Temperature: check every 4–6 hours with a thermometer
• How your child looks and acts: are they drinking fluids? responding to you? playing at all?
• Rash: any new spots or redness on the skin
• Breathing: faster than normal, working hard to breathe
• Wet diapers: fewer wet diapers means your child may be dehydrated

What you can do at home

• Give fluids: breast milk, formula, water, or diluted juice — small amounts often
• Dress lightly: one layer of clothing, light blanket if needed
• Fever medicine: acetaminophen (Tylenol) or ibuprofen (for children over 6 months) can help with comfort. Follow the dosing instructions on the package for your child’s weight — not their age
• Rest: keep your child calm and comfortable

Do not use aspirin in children under 18. Do not use cold baths or ice.
