Go to the ER Immediately — Regardless of Temperature

💤Febrile seizureConvulsions, stiffening, or uncontrollable shaking during fever. Call 911.
🕇Stiff neckDifficulty or pain bending the neck forward — can indicate meningitis.

💧Signs of severe dehydrationNo wet diapers in 8+ hours, no tears, sunken fontanelle (soft spot), very dry mouth.
🔴Lips or skin turning blue/greyCyanosis is a medical emergency. Call 911 immediately.
💕Any fever in a baby under 3 months38°C (100.4°F) or higher in a newborn requires immediate evaluation.

Age-Specific Fever Rules

Under 3 months (0–12 weeks)

Any temperature ≥ 38°C (100.4°F): Call your doctor or go to the ER immediately. Newborns cannot fight infection effectively and evaluation is always required.

3–6 months

≥ 38.9°C (102°F): Call your doctor. Below this threshold, monitor closely but watch for warning signs.

6–24 months

≥ 39.4°C (103°F): Call your doctor if it lasts more than 1 day without other symptoms, or immediately if accompanied by rash, difficulty breathing, or unusual behaviour.

2 years and older

Focus on behaviour, not just temperature. A child with a 39°C fever who is alert, drinking fluids, and playing is less concerning than a child with a 38.5°C fever who is very lethargic or has difficulty breathing.

Temperature Measurement Methods

Method	Best For	Accuracy	Notes
Rectal	Infants under 3 years	Most accurate	Gold standard for infants. Use lubricated thermometer, insert 1–1.5cm.
Oral	Children 4+ years	Very accurate	Wait 15 min after eating/drinking. Reliable if child can hold still.
Axillary (armpit)	Any age (screening)	Less accurate	Add 0.5–1°C for a rough rectal equivalent. Use for screening only.
Ear (tympanic)	Children 6 months+	Variable	Technique-dependent. Ear canal must be straight. Not reliable under 6 months.
Forehead (temporal)	Any age (quick check)	Least accurate	Useful for quick screening. Can be affected by sweating, environment. Confirm with another method if concerned.

General Fever Care Tips

Fever itself is not dangerous — it's the body's natural immune response. Keep your child comfortable: offer fluids frequently to prevent dehydration, dress lightly, and maintain a comfortable room temperature. You don't need to wake a sleeping child to give fever medication unless they seem very uncomfortable. Fever reducers help with comfort but do not treat the underlying cause.
