Play is a child’s main occupation – it is through play that they learn about the world around them and how to control their own bodies. Stacking toys help to teach them valuable balance and coordination skills, the baby or toddler learns to achieve balance not only with their own body but also by engaging with external objects such as toys. By controlling the movements of their hands and fingers, young children learn to manipulate individual objects. Babies as young as 6 months can practise moving components of the toys around and stacking them on top of one another, learning to control the precise movements of their arms and hands.
