Stacking toys stir the curiosity of children and teach them concepts of fitting pieces as per sizes and of comparing objects to one another while finding appropriate matches between various blocks of the toy set. Block play toys are advised to contribute to a developing child's self-confidence and of empowering them to find solutions. As an example, a baby in a nursery with their stacking blocks will sure feel self-confident and rather proud when they see themselves successfully stacking blocks or rings on one another, albeit as a part of the play.
