2 months baby 36.9 ℃ is not considered fever, belong to the normal body temperature.
Normal children’s body temperature according to the measurement of different parts of the body temperature, clinical commonly used axillary thermometry way to determine the body temperature, children’s normal body temperature range is about 36 ~ 37 ℃. Therefore, a baby’s body temperature of 36.9℃ is not considered a fever. When the baby’s axillary temperature exceeds 37.3 ℃, then consider the possibility of fever.
Normally, the body temperature of a normal person will not fluctuate more than 1℃. However, it should be noted that, due to the fact that infants and young children’s thermoregulatory center is still unstable, its heat dissipation activities and other relative imperfections, when there is overdressed, increased activity and other physiological conditions, its temperature fluctuations may be greater than the adult or even more than the upper limit of the normal body temperature.
Therefore, it is recommended to measure the body temperature again after a period of time for mildly elevated body temperature. If there is a persistent increase in body temperature, it is necessary to be alert to colds and other diseases, and then it is recommended to go to the hospital in a timely manner.
