BabyPlus introduces a safe, simple set of sounds to a child as early as 18 weeks in the womb. These sounds are patterned after the mother’s heartbeat, the one language the baby can recognize at this early stage of development. This is the only true and consistent sound of the prenatal environment. The BabyPlus sound patterns are varied through a series of lessons. As the baby starts to differentiate the sounds of their natural environment from the BabyPlus lessons, learning begins.
