Research shows that an unborn child has the capacity to feel, sense, hear, and communicate from as early as the twelfth week of gestation. For example, maternal fear and stress will affect a fetus’ activity in the womb, hard rock music will produce violently hyperactive movement, or a bright light over the abdomen will increase fetal heartbeat. Singing to your unborn child is a special form of communication that stimulates the physical, psychological, and emotional growth of the developing child. While singing folk songs, lullabies, or a favourite melody directly to your unborn baby, you may be surprised when he or she joins in on the fun.
