These play opportunities offer holistic, child-driven development, engaging large motor skills and fostering cross-hemisphere brain processing. Stacking and knocking down boxes brings joy, and also encourages resilience by building frustration tolerance. Finally, when children use their imaginations and their little hands to transform boxes into new play materials, they exercise agency, creativity, flexible thinking, and fine motor skills! Let your little ones be the architects of their play—where anything can be anything, especially with a simple cardboard box.
