6 months & up. Invite infants and toddlers to discover motion and sound with this set of Rollables™ Farm Friends. Each soft ball comes in an easy to grip size and creates a different sound when shaken or rolled. Little ones will develop foundational hand-eye coordination skills as they transfer the ball from one hand to the other and visually track the ball's path. These sensory soft balls create endless learning opportunities. Includes 4 familiar farm animals, cow, pig, horse, and chicken. Approximately 2.5" each. Wipe clean with a damp cloth.
