Children's folk music should be piped into a pediatric practice. Pediatric refers to the branch of medicine that deals with the medical care of infants, children, and adolescents.
Playing music for unborn babies is a common practice known as prenatal stimulation or fetal stimulation.

By the third trimester, the fetus's hearing is well-developed, and they can respond to sounds and music.
