Fisher-Price Baby Toy Stack & Roll Cups, 10-Piece Stacking & Nesting Activity for Developmental Play Infants Ages 6+ Months

Baby will love nesting the colorful numbered cups together, or stacking them higher and higher, or snapping them together to make colorful balls to roll! There's even a smiley jingle ball that nests inside any cup, or fits on top of the whole stack. Stacking, nesting, or snapping cups together introduces baby to size, shape, and how things fit together in a really fun way!
