A temperature of 37.5 degrees in a 2-month-old baby is not considered a case of fever because when the temperature is measured in the armpit, the normal temperature range is between 36 and 37 degrees. If the temperature is measured in the mouth, the normal temperature range is between 36.3 and 37.2 degrees. If the temperature is measured in the rectum, the normal temperature is between 36.5 and 37.7 degrees. Only if the temperature exceeds the normal temperature range by more than 0.5 degrees is it considered a case of fever, and the child’s body temperature tends to be slightly higher than normal, so 37.5 degrees is not considered a case of fever. At this time, you need to give your child more water and rest, and pay attention to your child’s mental state and changes in body temperature. If there is a persistent increase in temperature, it is a fever. If you have a cold, you need to give your child plenty of water and take cold medication, such as pediatrician’s pills.
