What is considered a fever for a 4 month old?

My 4-month-old baby is feeling a little warm, and I'm quite concerned. What temperature should I look out for to know if it's actually a fever for such a young infant? I'm a new mom, so I'm a bit unsure.

A rectal or axillary temperature of 100.4 F (38 C) or above is considered a fever for a 4-month-old baby. Because babies at this age have developing immune systems, it is highly recommended to consult your paediatrician immediately.

For a 4-month-old, a temperature of 100.4 F or higher is a fever. At this tender age, please do not try any home remedies or guess the medicine dosage. Contact your paediatrician right away for a safe evaluation.

My baby had a fever at 4 months and I was crying the whole night out of fear. A reading of 100.4 F is a fever. It is incredibly hard to see them sick, but please call your doctor, they will guide you and it will be okay.

When my baby was 4 months old, his doctor told us that 100.4 F is the fever threshold. Whenever his temperature reached that, we directly took him to the clinic as advised by our doctor.

Anything 100.4 F or above is a fever for a 4-month-old. Use a digital thermometer for accuracy. Keep the baby dressed in light cotton clothes and call your paediatrician immediately for the correct prescription.
