The Symphony Light & Motion Mobile stimulates and develops sight and hearing. With four different fascinating movements, it encourages baby to focus on an object and track it with her eyes. The combination of repetitive circular motion and other alternating movements with objects rising and falling and turning around, maintains baby’s attention and active observation. In addition, the alternating movement of the colorful liquids in the center, with or without the light, enriches the visual experience. The three different classical music tunes stimulate and develop hearing, bringing baby closer to the world of music and developing her musical skills. The combination of music and visual stimuli also develops coordination between these two senses.
