The answer is Yes and No.
"Most allergies are inherited, which means they are passed on to children by their parents. People inherit a tendency to be allergic, although not to any specific allergen. If a child develops an allergy, it is very likely that at least one of his or her parents has allergies.
Being exposed to allergens at certain times when the body’s defenses are low or weak, such as after a viral infection or during pregnancy, also may contribute to the development of allergies."
Hope this helped to answer anyone's questions re allergies and where they originate!
