first of all, i feel your pain--we're dairy-gluten-corn free. it's so hard to nurse and have your baby comforted and know he might be screaming or in pain 15 minutes later as a result. it's great if you've figured out what he reacts to, and i would recommend reading the food allergy cookbook it has lots of information and sibstitutions and keeping intake really basic. also probiotics for you and baby or digestive enzymes might help as well. i second find out if your pre-natal vitamins are allergen free. also, keep trying to reintroduce foods. It can take longer--a few days of exposre--when they get a bit bigger but it will give you a break and will help you see how is GI development is going. good luck!
