I have always thought that probiotics help with diarrhea in babies. But ever since my son has started taking them, his poop has been completely liquid. They weren't this way before. Anyone experienced this?
Oh and he is formula fed by the way.
Yes, a dose that is too high can cause that. It can also be caused by an organism that doesn't work well for a person. Our DS1 had this reaction to saccharomyces boulardii, the organism in Florastor. He does fine on probiotics without this organism. You may need to try a brand with a different mix of organism and/or a smaller dose.
