If you see no improvements, it would probably not be a good idea to try ghee since it may still contain some casein; however, if you plan on ``cheating" (which for my sanity I often had to do

, I would definitely use ghee instead of butter). I try to avoid all margarines, and a lot of things that have omega 6 (mamafish and ome other people had good results after reducing omega 6 without necessarily increasing omega 3). I would second everyone else and encourage you to dig a little deeper and try to find what the culprits are. Eggs, peanuts? Also, it is the case with our children that it is not a food, but rather different components: sallycilates, oxalates, phenol, etc. Look at the larger picture too: is it fruits, or carbohydrates that your baby reacts to? Also, different foods tend to give different symptoms, for example my dd used to sweat profusely and throw up from eggs, but she would get rashes, diarrhea from other foods. My DS reacts to sweet potatoes (probably oxalates), but he is
still pretty happy, so I did not exclude them from my diet, instead I eat less of them.
