37.6 degrees typically refers to a temperature of 37.6℃. Whether a temperature of 37.6℃ in a 6-month-old baby is considered a fever depends on the site of measurement.

Common sites for measuring body temperature include the armpit, mouth, and rectum. A normal temperature in the armpit ranges from 36 to 37℃, while a normal temperature in the mouth is between 36.5 and 37.5℃. The normal temperature in the rectum is between 37 and 38℃. Therefore, if a temperature of 37.6℃ is measured in the armpit or mouth of a 6-month-old baby, it can be considered a low-grade fever. This can be managed by physical cooling methods such as drinking plenty of water, applying a fever-reducing patch on the forehead, or using lukewarm water to wipe the forehead, armpits, and groin to lower the temperature. If the temperature is measured in the rectum, it generally does not indicate a fever and does not require any specific treatment.

When a baby experiences fever, it is recommended to promptly visit a hospital for relevant examinations. Once the specific cause is determined, appropriate medication can be chosen under the guidance of a doctor for treatment.
