New silk thread multi-layer color ball pendant: 26.5*21*4cm in size. Made by hand using natural silk thread, the five-color gradient spheres showcase the variations in shades of the same color family. It is specially designed for visual enlightenment of newborns aged 2-3 months Safe and natural silk material: The silk thread is lightweight, soft and non-irritating. The ball body has no risk of small parts falling off. The hanging line is firmly fixed and prevents entanglement. It needs to be fixed by an adult at a height of 30 cm above the baby's prone position for their line of sight Visual tracking and color perception: The gradually changing colored balls that sway in the wind attract the baby's attention and help them perceive color gradations and changes in brightness, 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 move the pendant to guide the baby to observe. Adjust the height according to the baby's reaction, and through this interaction, establish emotional connection and develop interest in sensory exploration
