(CNN) - Children seem to go from one illness to the next often making it hard for parents to determine what might be a cold or an allergy.
"Runny noses and sneezing are common to both colds and allergies," Dr. Jennifer Shu said.
But there are some distinct differences between the two conditions.
"Allergies can also have itching," she said. "Itchy or watery eyes, itchy nose, itchy throat and those tend to be hallmarks of allergic reactions.
You don't see much itching with colds.
But colds have a few symptoms that set them apart from allergies; and one of those is fever.
Children with a cold may develop an elevated temperature, but that is not the case with allergies. Youngsters often complain about a sore throat with a cold, something less common with allergies.
Also colds tend to run their course within a week or two weeks whereas allergies can last much longer.
"If you have a child who has symptoms typically every fall or every spring lasting for more than a couple of weeks…that's probably an allergy," Shu said.
And if your child's symptoms have you concerned, as always check with your pediatrician.
