I am agree on that. You can make the toys to be developing and fun both the child of any age. You just need to know what kind of the knowledge does the child posses and learns on each stage of his life. The kids from 1 year old, they are starting to learn to speak, to call different things by their own names, to distinguish colours etc. And there are toys that are made to make this task easier for the children. Different simple logical riddles, for example, like plastic boards with the holes of different shapes, and the plastic figures with similar shapes, each fits only to one of the holes.
