Stacking toys are colorful play items designed to help young children develop fine motor skills and hand-eye coordination. These toys typically consist of various shapes, such as rings or blocks, that can be stacked on top of one another. They encourage creativity and problem-solving as children figure out how to balance the pieces. In addition to physical skills, stacking toys also promote cognitive development. As children play, they learn about concepts like size, order, and balance. Popular examples of stacking toys include the Fisher-Price Stack 'n' Sort® Toy and Melissa & Doug Wooden Rainbow Stacker.
