Fever in Babies

One of the symptoms the parents scare most is fever in babies. The scariest is when that fever is high or the baby is only a few weeks old.

Fever isn’t an illness, it’s considered a symptom of one. Fever usually indicates that the body is fighting an illness and the immune system is functioning. Causes of fever in babies include:

  • Picked up cold
  • Viral infection
  • Reaction to a vaccination
  • Overheated by overdressed
  • Spending too much time outside on a hot day

And here are the signs when your baby is in fever:

  • Warm forehead
  • Crankier and fussier than usual
  • Poor sleeping
  • Poor eating
  • Less active
  • Convulsions or seizures

When your baby is showing the few signs above, it is the best that the parents take the baby’s temperature to confirm the symptom. There are few ways to measure a baby’s temperature, such as via the rectum (rectally), mouth (orally), ear, underarm (axillary) or at the temples. Rectal temperature readings are the most accurate, and can be the easiest to take in infant. Typically, babies can’t hold an oral thermometer in place, and the reading of an ear, temporal, or underarm thermometer are not as accurate.

A baby’s normal temperature¬†inside your baby’s body is usually around 37 degree Celsius. Your baby has a mild fever if the temperature is higher than 38 degree Celsius. A high fever usually means more than 39 degree Celsius.

The American Academy of Pediatrics (AAP) recommends only using digital thermometers in children. Mercury thermometers should not be used because there is a risk of mercury exposure and poisoning if they break.
