Temperature measurement for infants is usually the most accurate for anal temperature measurement, but it is easy to cause harm to the baby, so the axillary measurement is mostly used to measure the temperature. There are usually three ways to measure the temperature of infants, namely, axillary measurement, oral temperature measurement and anal measurement. Among them, the anal measurement method is the most accurate, but it needs to take the correct measurement method to avoid causing damage to the baby’s anus. The oral temperature measurement method is easily affected by eating and other dietary influences, and is relatively unsafe. Therefore, axillary measurements are commonly used to measure body temperature in infants. The axillary measurement is usually more convenient, and is safe and hygienic.
