What if a 5-month-old baby has a fever of 38°C?

A fever of 38°C in a 5-month-old baby can be worrying for parents. First, it's important to know: a baby's fever is a sign their body is fighting an infection — it's not always dangerous.

However, when evaluating fever in a 5-month-old, there are two critical age thresholds:

* In babies under 3 months: A fever of 38°C or higher requires urgent medical evaluation. This age group has very weak immunity, and it could be a sign of serious infection.

* In babies 3-6 months old (your 5-month-old falls into this group): A fever of 38°C is generally not a cause for immediate panic, but you should consult a pediatrician the same day. Along with the fever itself, your baby's overall condition is very important.

What should you do?

1. Watch your baby's overall condition: If despite the fever, baby seems happy, playful, feeding well, and has normal wet diapers, that's usually a good sign. If baby seems uncomfortable, very sleepy, not interested in food, or listless, this situation needs more attention.

2. Take temperature correctly: The most reliable method is rectal temperature measurement. Armpit temperatures are usually 0.5°C lower.

3. Non-medication measures: Don't overdress baby; keep room temperature around 21-22°C; encourage fluid intake (breast milk or formula). A lukewarm bath (around body temperature, 36-37°C) can help; never use cold water.

4. Medication use: Never give fever-reducing medicines (acetaminophen or ibuprofen) without doctor advice and without knowing the dosage. Dosage is adjusted by baby's weight.

When to see a doctor immediately (emergency signs):

* Fever rises to 39°C or higher.

* Baby has seizures (convulsions).

* Baby has difficulty breathing or lips are turning blue.

* Baby seems extremely weak, can't be roused.

* Vomiting won't stop or diarrhea is severe.

* Red dots on the body that don't fade when pressed (petechiae/purpura — these spots don't disappear with pressure).

In short: A 38°C fever in a 5-month-old isn't reason to panic if baby's overall condition is good; however, you must see a doctor the same day. If 'red flag' symptoms accompany the fever (especially non-fading rash), go to the emergency room immediately.
