My baby's fever goes up every night and comes down on its own in the morning. What does this pattern of coming and going fever indicate?

A fever that rises every night and drops each morning is typically seen in viral infections. The body increases its immune response as the day progresses, which is why fever peaks in the afternoon or evening. The fever itself is not an illness but your body's defense mechanism fighting an infection.
However, if this pattern doesn't resolve within 24-48 hours without treatment, or if additional symptoms appear (lethargy, loss of appetite, breathing difficulty, vomiting, rash), you should definitely see a pediatrician. The source of the fever needs to be identified (urinary tract infection, middle ear infection, pneumonia, for example) through evaluation.
Remember: especially in a baby younger than 3 months, if fever is ≥38°C — regardless of the pattern — call 112 or go to the emergency room immediately.
