Everyone is telling me that both of my children (5 and 1) could have allergies. they both have had several "colds" within the last few months and they always get it at the same time. I don't have allergies myself, but I always assumed that you would have allergy symptoms throughout the entire allergy season. but am I wrong? Do the symptoms come and go?

It depends on what that particular person is allergic to and how much of the allergen that person is exposed to. Like pollen from trees and plants at certain times of the year can be worse than at other times and if your children come close to that pollen or allergen, they may have an attack raising the symptoms.

Symptoms do come and go, depending on what pollen is in the air and how high the pollen count is. Spring and fall are the worst time for allergies.
