Started Nutramigen fortification

We started Nutramigen fortification this evening. He took it without complaint which is a good sign. I think it smells and tastes like stale cardboard. We are adding 1/2 teaspoon to 3 ounces of milk. Nutramigen has modified milk proteins that are not supposed to cause problems for babies with cow's milk allergies. He has been doing so well with his reflux since I went off of dairy we shall see how he does with the Nutramigen.
