The baby's temperature has been consistently between 37.2 and 37.4 degrees Celsius.

The baby's body temperature consistently ranging between 37.2°C and 37.4°C may be due to physiological factors or pathological factors, such as viral cold or chronic tonsillitis. Appropriate management should be selected based on the specific cause.

I. Physiological Factors

This may occur due to high ambient temperature, intense physical activity, or increased levels of movement in the baby, leading to faster blood circulation. This condition is generally considered normal and the body temperature usually returns to normal after rest.

II. Pathological Factors

1. Viral Cold
In cases of a viral cold, the body's temperature regulation center is affected, causing the temperature set point to rise. Under a doctor's guidance, medications such as ribavirin granules, ibuprofen granules, or antiviral granules may be used for treatment.

2. Chronic Tonsillitis
If caused by chronic tonsillitis, inflammatory factors enter the bloodstream, resulting in an elevated temperature set point. Under medical supervision, treatments may include ribavirin tablets, oseltamivir phosphate granules, or cefaclor granules.

Besides the above, conditions such as endocarditis could also be responsible. It is recommended to seek timely differential diagnosis and follow medical advice for appropriate treatment.
