Baby fever at night is a very common phenomenon, the baby is fine during the day, wait until the evening began to fever, even to the extent of high fever, the next day and normal, some mothers will think that the child is intermittent fever, in fact, it is necessary to emphasize the point that the fever at night, normal during the day, still to say that this child this day is feverish. There are several possibilities, for example, there are children who have a fever but are in good spirits, play around during the day, do not feel it, and the mother does not give a temperature measurement, and only when they start to rest at night will they quietly try their temperature and find a fever. Other children who eat too much food at night causing food accumulation are also prone to have a higher temperature at night, but it is still important to pay attention to it rather than being able to ignore it. In general, babies’ endogenous hormone levels are lower at night than in the morning, so it is possible that fever is a little more common at night. If a child is a little hot and in good spirits overnight, then you can let the child rest and observe the next day, and if the fever is present every night, you must seek prompt medical attention. In addition, nighttime fever can be very inconvenient if you need antipyretic treatment, so parents with babies should usually have some antipyretic medicine at home to avoid being helpless when you encounter a fever in your baby.
