When to Call the Pediatrician? Alarm Symptoms in Babies
The difference between "I'll see tomorrow" and "going to the ER now". Quick guide by symptom.
Every first-time parent's fear: is this normal or do we need to go to the ER? The answer depends on the baby's age and the combination of symptoms, not just one. A 2-week-old with a 38°C fever is an emergency. A 9-month-old with the same fever can probably wait until morning.
GO TO THE ER NOW: don't wait
Baby under 3 months with fever ≥38°C (rectal)
Difficulty breathing: nasal flaring, chest retractions, bluish color on lips
Seizure (rhythmic movements, loss of consciousness)
Not responding to stimuli, extremely lethargic, or inconsolable for more than 2 hours
Fontanelle (soft spot) newly bulging or sunken
Blood in stool or projectile vomiting repeated in a baby under 4 months
CALL YOUR PEDIATRICIAN TODAY (not ER, but soon)
Fever >38.5°C in a 3-6 month old
Fever >39°C in a 6+ month old lasting more than 2 days
Not eating for 8+ hours (breastfed or formula-fed baby)
Fewer than 4 wet diapers in 24h (sign of dehydration)
Crying different from usual — high-pitched, unusual, inconsolable
Pediatrician's rule: if something seems "very different from normal" in your baby, trust your instinct and call. No one will scold you for an extra call.
