The normal underarm temperature of a full-term baby is between 36℃-37℃, and a child’s body temperature within this range is considered normal. In addition, children’s body temperature fluctuates throughout the day, most of the day fluctuation range is not more than 1 ℃, and children’s armpit temperature and the amount of clothing worn also has a different degree of influence. If too much clothing is worn, it can also cause a slight increase in axillary temperature. In addition, if a child wears too little clothing in the cold winter, it will often cause a slightly lower axillary temperature, which is a physiological phenomenon. Children’s body temperature fluctuates little, and if it exceeds 37.5℃ in the armpit, it is considered feverish.
