How many days does it usually take for a baby's low-grade fever to subside?

Baby's low-grade fever refers to a body temperature slightly above the normal range but not meeting the criteria for a fever. The duration for the fever to subside varies depending on the underlying cause and individual differences. 1. Low-grade fevers are commonly caused by mild infections or inflammations, such as colds or upper respiratory tract infections. In such cases, the low-grade fever usually resolves on its own within a few days. Monitoring the baby's overall condition, if symptoms are mild, body temperature typically returns to normal within 3 to 5 days. 2. A low-grade fever may also be related to environmental factors or excessive fatigue. Adjusting the baby's living environment, such as maintaining an appropriate room temperature and humidity, and ensuring the baby gets sufficient rest and proper nutrition, can help shorten the duration of the fever. 3. If the low-grade fever persists for more than a week or is accompanied by other severe symptoms, such as loss of appetite, persistent crying, or changes in mental status, prompt medical attention is required.
