When To Call Your Doctor When Your Child Has a Fever

Fever itself will not harm your child and does not necessarily require treatment. But, you should call your pediatrician if:

Your child is under three (3) months of age and has a rectal temperature of 100.4 (38 degrees C) degrees or higher.
Your child is lethargic (the state or quality of dullness, prolonged sleepiness, sluggishness, or serious drowsiness) or irritable.
Fever has been present for longer than three (3) days.
Your child also has symptoms such as sore throat, ear pain, abdominal pain, or pain when urinating.
Your child is drinking less fluid than usual and has had a fewer than four (4) wet diapers in the past 24 hours or two (2) urinations during waking hours.
You are worried your child is less active than normal or is having trouble breathing, whether or not he/she has a fever.
