This sensory grasp ball has a perfectly scaled Dalmatian pattern to support your baby's visual development and capture their attention. The segmented shape makes it easy to grab, hold or throw - encouraging gross motor skills and hand-eye coordination. The hook makes it easy to attach to a link or a strap (not included) to add to the baby gym, stroller, or car seat for contented staring and play. Made in organic cotton with a central bell to help drive babies' understanding of cause and effect (when I do this, this happens) to make the perfect first toy. Made from organic cotton outer with recycled polyester fill including bell. Ages 5 months and up. Measures 5.11 in. diameter.
