Query: Caused too much gastric upset in our baby to continue using

I spent so much time trying to figure out what was causing all the extra gas in our baby. I knew it was my milk but when I stopped taking these tablets we learned it was this product that was causing all the crying and gassiness. It kind of helped my milk supply flow but it wasn't worth not sleeping from a constant crying and pooping and gassy baby. I gave it a three star since I feel as though it did work but our baby did not tolerate it for sure.
