My mom used to have listen to classical music when I was a baby. She said that it made me shut up. Either I really liked it or I was bored. She insisted though that it was very effective to calm me down, but not always because sometime I would cry as if I was feeling for the music. This culture have run in our family for over many generations. My uncles also do the same thing to my baby cousins. And my grandmother used to do it to her kids, to my mom and to my uncles. They insist that it really has good positive effects for cognitive development. In short it makes babies grow up and develop smart.
