This soft, squishy rattle is perfect for baby. The bright colours, different materials, and variety of surfaces help stimulate baby. Even the neck of the rattle aids in baby's development by flexing 180 Degree, providing a perfect manipulation challenge for little hands. In the sphere of the rattle are contrasting black & white beads that stimulate baby's developing vision and awaken auditory awareness. Additionally, the brightly colored click-clack rings provide auditory stimulation, while the textured handle is great for mouthing.
