Probiotic Drops & Gas

Patti
For those using the drops, are any of you using them on your LO for gas issues? Mine has had gas problems from his first week on.  We've tried so many different formulas and are on Alimentum now, which doesn't really help. We use the gas drops, gripe water...no relief there either. I'm just wondering if I should try out the probiotic drops for the gas. His doctor didn't have many more solutions to offer other than to continue with the Alimentum and also prescribed medication for reflux, but we still haven't seen a change for the better :(
