My DD's are both allergic to cow milk protein, DD2 is reactive to soy, and DD1 oats. Both had issues with bananas and anything high in salcilytes. I put them on an elimination diet and we found alot of what they reacted through. We also saw an allergist whilst doing all of this. I followed the Fail Safe diet at first to rule out preservative reactions. I remember the first few weeks spending hours in the shops reading labels. It was very daunting.

We have not had dairy, cheese, anything in over 3 years now. We eat heaps of broccoli, spinach, sesame seeds (extremely high in calcium but also a high allergen food), and use multivitamens to help with calcium intake. Magnesium is very important when ruling out dairy, as it is what the body uses to absorb calcium and no matter what the foods calcium value is, without magnesium its not worth it.

My DD's both had reflux symptoms as well, my DD2 was 9 weeks old when I saw a Lactation Consultant who helped with going on an elimination diet and stopping dairy in my diet in order to breastfeed her. When she was 6 months and starting solids, we became very serious about the elimination diets and seeing an allergist. I suggest going through an allergist or dietician as MantaRay said. Its a hard journey, but much worth it!
