Fever in the First 30 Days

  • Fevers in children seem to cause caregivers a great deal of anxiety.
    • This stems from two factors.
      • Fevers are frequently uncomfortable. If you can remember the last time you had a fever, I’m sure you would agree. You have no energy. Your muscles ache and your head hurts. You don’t want to eat or drink anything, and you can’t sleep. This happens with children as well, and it worries caregivers to see them so miserable.
      • here are a great deal of inaccuracies and myths suggesting that fevers are dangerous. The truth, however, is that fevers are not dangerous, even when they are very high. They simply tell us there is an infection. In children 1 month and older, what really matters is that they are responsive, hydrated, and breathing comfortably.
  • In children younger than 1 month old, it’s a different story. Before 1 month of life, a fever must be discussed with a medical provider. The fever itself is still not dangerous. The concern is that their immature immune systems may have contracted a potentially life-threatening bacterial infection, which could be hiding in the blood, lungs, urinary system, or even the spinal fluid.
  • The provider may need to send these babies to the emergency department, where the work-up can include blood and urine cultures, or a spinal tap looking for meningitis. Because so much is riding on the temperature, you should follow different recommendations if your baby is younger than 1 month old.

Rectal Temperature

  • The only way to take a temperature in a child younger than 1 month old is rectally
    • We must have the most accurate reading possible, and research shows that other methods are less reliable and accurate.

Only If You’re Worried

  • Avoid taking the temperature unless your baby is doing something new that worries you.
    • For example, if they won’t stop crying no matter what you do, or they stop feeding or peeing normal amounts.
    • Feeling warm is not a reason to check the temperature if nothing else is concerning.
      • Neither is checking once a day or every few hours because this was done in the delivery hospital.

Numbers to Know

  • 100.4ºF
    • any rectal temperature 100.4ºF or higher is a fever.
    • This is the case for anyone, regardless of age.
  • 97ºF
    • any rectal temperature below 97ºF is the same as a fever if your child is younger than 30 days old.

What to Do

  • If your child is younger than 30 days old, has a rectal temperature 100.4F and higher or less than 97ºF, and you checked it because you were worried, contact a medical provider immediately.
