|According to the American Academy of Pediatrics, a fever is typically caused by either bacterial infections (such as strep throat or ear infection) or viral infections (such as cold or flu). In the event of a fever, making your child as comfortable as possible is important. Look for changes in behavior such as excessive fussiness, flushing, paleness, or other signs of discomfort in your baby. Take your child’s temperature with a thermometer to indicate if your child is running a fever—feeling the skin is inaccurate, especially when your child has a chill. Consult your pediatrician for information specific to your child.
