Food allergies in children have been on the rise for years. Estimates show that between 2 and 10 percent of all kids in the United States have at least one, and peanut allergies are thought to be the most common.
My 6-year-old son was born with a peanut allergy, but a blood test now shows he's no longer sensitive to it. How is this possible? And is it really OK to give him peanuts again?
