This section is intended to serve as a handy reference guide and starting point for understanding and distinguishing children’s basic abilities and preferences as they grow. These abilities and preferences play an important role in attracting and motivating children to interact with toys. Developing physically, for example, changes the ways in which children are able to coordinate their gross-motor skills. Increased mobility opens up new ways to use toys. A higher level of fine-motor skill permits greater manipulation of objects. Ultimately, such knowledge helps to identify and distinguish the characteristics of toys that are appealing to children at a given age.
