Fever is a form of defense of the organism and in some cases it can appear and disappear within 24 hours or remain for more days. The fever that comes and goes in the baby is common and is one of the ways of the organism to signal that something is not well. This type of fever can cause confusion for parents, because when they think it is resolved, the fever comes back.
Although fever is one of the manifestations that most generates anxiety in parents, especially in newborns, when it comes and goes it is usually related to less serious situations such as reaction after taking a vaccine, the birth of teeth or even excess clothes in the drink.
The baby is considered to have a fever when the temperature exceeds 37.5ºC in a measurement in the armpit, or 38.2º C in the rectum. Below these temperatures, there is generally no cause for concern. See more about how to know if it is fever in the baby.
