The baby is not in good spirits today, he doesn’t even want to eat dinner, his face is red, his mother took his temperature, 37.8 ℃, a little low fever, as a mother, the child has a fever, a heart can not fall. The only way we can take better care of our babies and put our minds at ease is to know more about fever. Here’s what you need to know about fever. What is a child’s normal body temperature? Your child’s normal body temperature (axillary temperature) usually fluctuates between 36 ℃ and 37.3 ℃. The phrase “fluctuates” means that a child’s normal body temperature is never fixed. After feeding or exercising, your child’s body temperature may rise higher. However, as long as the child is in good spirits, seems happy, and is not uncomfortable, his or her temperature can drop after a short rest. Occasionally, a temperature that is “over the limit” once or twice does not have much effect and cannot be considered a fever. Fever is not always a bad thing In the eyes of pediatricians like O’Shea, fever is usually just a normal protective reaction of the body, which not only does not have serious effects on the body, but also improves the body’s ability to resist and helps the child recover. Moms and dads always feel that their children need emergency treatment when they have a fever. Some parents also mistakenly believe that a fever will “burn into pneumonia” and “burn the brain”, in fact, these concepts are not based on science at all, just misunderstood by everyone. The higher the temperature, the more serious it is? Before answering this question, let’s take a look at the classification of fever according to body temperature: 1. < 38 ℃ for low fever; 2. 38-38.9 ℃ for moderate fever; 3. 39-41.0 ℃ for high fever; 4. > 41.0 ℃ for super high fever. Except for very rare cases of super high fever, in most cases, fever does not cause harm to the child’s body. Some children, even with a mild infection or vaccination, develop a high fever; while some children may not have a high temperature even though their condition is serious. The child’s mental state is a better indicator of the severity of the illness than the thermometer. For example, a 3-year-old child has a fever of 39 ℃, but her life is no different than usual, she eats, plays, sleeps, and even claps and sings children’s songs with her father while waiting to be seen. In this case, there is no need to wake the child from sleep in the middle of the night and rush her to the emergency room. For children younger than 6 months old, parents should pay more attention if they have a fever and are reluctant to feed, are restless or irritable, or have shortness of breath than usual. Because small babies, especially newborns, can be very sick even if they have a small fever, it is important to see a doctor in a timely manner. How can I tell if my child has a fever? When a child has a fever, the mother asks herself: When did the fever start? When was the last time the temperature was taken? How does the baby look? Is he or she different from usual? Are the baby’s eyes bright? What did I do after the fever and did these things help? Is the baby uncomfortable anywhere else besides the fever? After sorting out all the questions in your head, you will often be able to make the right judgment.
