It's the only thing that works for our baby's gas. We've been using it since he turned three months with every feed. The instructions are a bit confusing, because it says you have to administer before a feed but up to a maximum of three droppers, but our doc. said it was fine before every feed. I like that there are no side effects and that it isn't absorbed into the system. If you don't use it before every feed, it won't be effective. Baby loves the taste -- he brings it to his mouth when he sees it out. We have used it for almost two months now.
