You may want to try gluten-free products. Although oats don't technically contain gluten, they are often left out of gluten-free foods because they are common cross-contaminants. I have found that the organic companies are much more likely to carry allergen-free things (Earth's Best, etc.), including eggs. How do I know? Because my 5-year-old son has been allergic to gluten, peanuts, tree nuts, eggs, seafood, and soy since he was 3 months old. Good luck to you!
