Graduated color ball visual hanging decoration: Made of soft gradient color spheres (about 5-6 per set), specially designed for newborns aged 2-3 months. Through the variation of colors in depth and lightness, it stimulates visual development and initiates the enlightenment of aesthetics Safety suspension material and manufacturing process: The spherical part is lightweight, non-toxic, and odorless. The suspension lines are sturdy and free from entanglement. There are no sharp components overall. It requires an adult to suspend the baby at a height of 30 cm above the baby's line of sight to ensure safe viewing Visual tracking and color perception: The gradually changing colored balls that sway in the wind attract the baby's gaze and help them perceive the changes in brightness within the same color family, thereby enhancing their visual focusing and dynamic tracking abilities Sensory integration and aesthetic cultivation: The gentle color transitions convey natural beauty, and through repeated viewing, they promote the development of visual nerves and subtly cultivate early aesthetic perception Parent-child interactive growth experience: Adults can gently touch the pendant to guide the baby to observe. Through this interaction, a bond of emotion can be established. The height can be adjusted according to the baby's reaction to meet their individual visual development needs
