While there are many tapes designed to stimulate a baby's mind, Brainy Baby is unique in addressing left and right brain functions in distinct programs. Called "whole brain thinking," the theory is that if children are stimulated to use both sides of the brain--preparing them to think logically and creatively--they will become more adept at learning and problem solving. Capitalizing on this research, the folks at Small Fry Productions (makers of Bilingual Baby) have produced a two-volume set to develop the whole brain. Volume one helps stimulate the right brain, which research shows is the center for creativity, intuition, and imagination.
