During the first 2 years of a child’s life, most parents feel uncomfortable and inadequate in determining how sick their infant is during a cold or other infection. Since the sick infant can’t talk, he can’t help much with the diagnosis. How sick your child looks or acts is much more relevant than the level of fever. Also, a child may look much better 30 to 40 minutes after the fever is reduced with medicine. When should you call your child’s health care provider?
