Infant body temperature if the oral temperature is generally 36.2 ℃ ~ 37.3 ℃ normal, axillary temperature 36 ℃ ~ 37.2 ℃ normal, anal temperature 36.5 ℃ ~ 37.5 ℃ normal. The normal body temperature of infants is mainly related to the measurement site, the measurement site is generally measured by the oral measurement, axillary measurement and anal temperature measurement, while the anal temperature measurement range is relatively high, the more commonly used is the axillary measurement of body temperature. The axillary temperature is generally 36 ℃ ~ 37.2 ℃ normal. When measuring the temperature of the infant, it should be measured in a quiet state. If the axillary temperature is more than 37.3℃, it means that the infant has fever symptoms, and it is necessary to clarify the cause of the fever and treat the symptoms and causes. In addition, we should pay attention to keep the baby warm, avoid the baby to be cold, otherwise it is easy to cause fever.
