Is it OK to play guitar while pregnant?
Not at all. Any healthy activity that you enjoy or find relaxing while you are pregnant will have a positive effect on your baby. Further, if you sing along while you listen, your baby hears your voice and develops familiarity with what you sound like and with the melodies you enjoy.
