Infants and toddlers have fever in a variety of situations such as colds, inflammation and indigestion. Low fevers have less impact and can rely on their own immunity to recover. The distinction between infant and toddler fever is more detailed, usually the baby’s body temperature at 37.3 ℃ to 38 ℃ is low fever, while a moderate fever is 38.1 ℃ to 39 ℃, 39.1 ℃ to 41 ℃ is high fever, and more than 41 ℃ is super high fever. Generally, low fever has little effect on the body of infants and toddlers, while high fever and above need to be sent to the doctor for treatment. A slightly high body temperature in infants is not always due to disease. If the axillary temperature is in the low fever stage, but the anal temperature is below 38℃ after measurement, it should not be considered a fever. If your baby has no uncomfortable symptoms and is eating and excreting normally, you can not worry about it. If the baby does have a low fever, there is no need to rush to take medication and injections first, drugs are more damaging and affect the liver and kidneys of infants and young children, in this case, you can rely on the baby’s own immunity to heal itself and help it strengthen its resistance and establish a perfect autoimmune system. What parents need to do is to give more hydration and closely observe the changes in their body. If the temperature rises, physical cooling is needed to avoid high fever. A baby with a temperature below 38°C is considered to have a low fever. At this time, the baby should be well taken care of, observe the temperature changes and cool down in time, and seek medical attention if the temperature is too high.
