Query: Perfect for my son's sensitive tummy.

We HAVE to use alimentum because my son has and intolerance to the milk protein casien. In fact I breastfed exclusively for the first 6 months and I had to eliminate dairy from my diet to avoid reactions in my son. So when we were looking for a formula alimentum was the one. Of course the negative is that it's so darn expensive but when it comes to a happy, healthy baby price comes second.
