Newborn Illness - How to Recognize


Does this describe your child's symptoms?



  • This guideline covers the subtle ways that infection and other serious diseases can present in newborns (birth through 30 days)

Why Newborns Need to be Observed Closely

  • Newborns are at increased risk for infections, especially during the first 7 days of life.

  • Newborns who develop bloodstream infections (sepsis) can deteriorate rapidly.

  • The symptoms of serious illness in newborns can be subtle and atypical. That is why the statement "Age under 1 month old (newborn) and starts to look or act abnormal in any way" is found in the "Call Your Doctor Now" section of at least 10 topics.

  • Feeding behavior is the one universal and reliable measure of a newborn’s well being.  Newborns should be vigorous eating-machines. If your baby has an abrupt change in his feeding pattern or isn't feeding well, call your baby's doctor. (EXCEPTION: never a vigorous feeder, but takes adequate amounts and nothing has changed).

  • If your newborn's appearance or behavior changes and you think it's abnormal, don't hesitate to call your baby's doctor now for expert advice.

If not, see these topics

    • Your baby starts to look or act abnormal in any way

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
