The child’s body temperature fluctuates in a wide range and varies depending on the measurement site, and the normal range may also vary. Generally, body temperature is measured in the armpit, 35.9 to 37.2 degrees Celsius in children at the armpit, and 36 degrees Celsius in children, which is the normal body temperature. 36 degrees belongs to the acceptable range and can be seen in physiological temperature fluctuations or normal basal body temperature. 1, physiological temperature fluctuations, children are easily affected by environmental factors, especially newborns, when the baby is cold, sweating, clothing wrapped thin, inadequate feeding, limited warmth measures, etc., will appear physiological temperature fluctuations, can wait until the above factors are lifted, interval half an hour to measure the temperature again, such as back to normal, then more belong to this that situation, but the follow-up still need to monitor the temperature changes. 2, the normal basal body temperature, no need to deal with. In the process of daily care, appropriate clothing, ensure feeding, ensure adequate energy supply, drink warm water in appropriate amounts, etc., monitor temperature changes. Whether it is a physiological temperature fluctuation or a further decrease or increase in body temperature fever, it needs to be taken seriously. If the body temperature continues to rise, it is necessary to give antipyretic treatment according to the body temperature; conversely, if it further decreases, it can be treated by strengthening warmth and feeding warm boiled water.
