“A child whose rate of development is slower than usual in one or more areas is in particular danger. The slow performers are as a rule made to practice something for which they are not yet ready. The child is passively placed into so-called more developed positions, he is expected to perform more and more developed achievements. He is asked to do things when he is not yet able to perform them by himself. Quite often sound and healthy children of slower pace of development are in this way turned into helpless, clumsy, butterfingered ones.”  – Dr. Emmi Pikler
