People used to believe that how a child turned out was predetermined. All children do seem to follow the same stages of development and in the same sequence. But, those whose life circumstances have been more favorable, and who have had a more enriched learning environment, progress more rapidly than those whose opportunities for learning have been limited. As evidence accumulates regarding the importance of the early years, there is increasing need to focus attention on the child’s experiences and environment.
