ABSTRACT
An only child has only adult ‘copy’. He cannot interpret his father's actions, or his mother's oftentimes. He imitates very blindly. He lacks the more childish example of a brother or sister near himself in age. And this difference is of great importance to his development. He lacks the stimulus, for example, of games, in which personification is a direct tutor to self-hood … And while he becomes precocious in some lines of instruction, he fails in wealth of imagination, in variety of fancy.
