Sidonie Matsner Gruenberg, Your Child: Today and Tomorrow
“ The child is now old enough to understand that some things are not to be had, and that crying for them will not bring them. To offer him a substitute is now not only an insult to his intelligence, but it is demoralizing to his will; it makes for a loose hold upon the object of his desire—and it is the firmness of this hold that is the beginning of a strong will. It does not take the child long to learn that he is not to have a knife or a lighted lamp; nor does it take him long to get into the way of scattering his desires, so that he has no will at all. ”
