I know the cause of all these crazy allergies is still unknown, but did you avoid peanuts while pregnant? Wagon Sr.'s cousin (who is a pediatrician) ate peanuts by the sackful with her first, and her daughter is severely allergic to peanuts (can't even be in a chinese restaurant because of the peanut oil they use in the food). She avoided peanuts altogether with the second and her son isn't allergic. Of course it could totally be a coincidence, but as I'm sitting here munching on peanuts (and thinking about a peanut butter sandwich, too) I'm wondering if I should be being more careful...
