Question
Why does my son have a high fever at night when he was fine during the day?
Answer
A baby’s normal body temperature ranges from 36 to 37.5 degrees Celsius, with the best range being between 36 to 37 degrees. A temperature above 37.5 degrees is considered a low fever, and anything above 38.5 degrees is a high fever. Fevers are generally categorized as either ordinary fevers or those caused by viral infections.
