From what I understand, you don't need to give a goat milk formula, just goat milk. Goat milk can be purchased at pretty much any grocery store anywhere. I'm not sure what procedures you have to take, if any, to prepare it for a baby. Goat milk is supposed to be very close to human milk and healthier and more nutritious for babies than formula. You could try looking it up to see what info you can find. Here are some links I pulled up at a glance, but I haven't read through each one thoroughly. Dr. Sears recommends it!
