Fever in Babies: When to Relax and When to Call

Fever is not an illness — it is the body fighting one. The number on the thermometer matters less than the baby's age and behavior.

🔹 The one absolute rule
Under 3 months old + temperature of 38°C (100.4°F) or higher = call the doctor or go to emergency now, even at 3 a.m., even if the baby looks fine. No exceptions at this age.

🔹 3–6 months
38°C+ deserves a doctor call the same day. Watch behavior: is the baby feeding, having wet diapers, and calming in your arms?

🔹 Over 6 months
Behavior beats numbers. A playful baby at 38.5°C is usually safer than a limp, unresponsive baby at 37.8°C. Offer fluids often, dress them light, and use doctor-approved fever medicine for comfort — not to chase a perfect number.

🔹 Go to emergency at any age if
Trouble breathing, a rash that does not fade when pressed, a stiff neck, unusual drowsiness, signs of dehydration (no wet diaper 8+ hours), or a seizure.

Keep a working thermometer at home and measure before calling — the first question will always be: how high, and since when?
