Bought this after reading so many positive reviews of babies spitting up less, having less gas, sleeping better, being happier, etc. My baby has been using it about 3 weeks now and I have not seen a difference at all. In fact, her symptoms are peaking right now. She is the gassiest she has ever been, unable to settle and sleep for longer than an hour at a time, and has terrible gas/spit up issues. This product may be working to improve her gut health, but I surely hoped it would have noticeable benefits by now. I will not be purchasing this product again, I’m going to move on to another brand.
