educating baby as fetus

aleхιѕ • VERY proud mother!! Married тo мy вeѕт ғrιend, and perѕυιng мy D.N.M. (docтor oғ naтυral мedιcιne)
I was looking on amazon and I saw these kind of like headphones that you put on your belly for the baby to listen to. I was wondering, has anyone come across any programs to help the baby while still in womb?
