I should mention I tried all of the above lol I tried Infants Friend & that worked really well, Infacol was okay it tends to combine all the bubbles together so you get one HUGE burp and that would always being up food with my refluxy baby, and Gripe Water which was okay as well.

The other thing that helped was Marina's mixture. But I do think some of these have a 1 month old limit on them, so check them out
