For those moms out there with infants or young children, this method is good for settling those upset tummies. My husband is really involved in Brazilian Ju-jitsu. The Gracie family is a family that came up with a form of this particular martial arts. The man in this video is a member of the Gracie family. His technique talks about getting the gas out of infants. I have used this on the twins as well and it works great too!
