I assume the stool has been cultured for Clostridium Difficile? Do you know what probiotic the baby is on? I would make sure it includes lactobacillis rhamnosus GG strain...not just acidophilus. With the heavy antibiotic use, bifidobaterium and other lactobacillus strains would be good too. Is the baby unhappy? Growing well?
