Oh, man how unfortunate that the doctor recommended Enfamil...First I would change Doctors. Then go and get some Organic Pastures raw milk, they are the cleanest and best form of raw milk commercially available I know (call them to learn more).
The question of pasteurized verses raw seems like a far gone conclusion in my experience and research. We don't need to pasteurize our mothers milk before we feed it to our kids at a young age, do we? The logic behind pasteurization makes sense from a large and dirty industrial production model, yet has not guaranteed the lack of contamination and even the prevention of deaths.
I strongly believe that pasteurized milk (or any heating of raw milk products) is more of a health risk than properly produced/handled and consumed raw milk product. (such as lifelong immune disorders, heart disease, degenerative digestive disorders, allergies...)

Raw milk Kefir is likely the most amazing food humans have discovered. If there is any potential for contamination, a proper ferment will ensure the beneficial bacteria have a stronger foot hold and will prevent any pathogenicity.
