Quote from : Montessori from the Start: The Child at Home, from Birth to Age Three Book

Parents in the early half of the twentieth century were primarily concerned with the development of character in their children. They wanted to be certain that their children were ready to cope with adversity, for it was surely coming to them one day whether in personal or national life. The development of character involves self-discipline and often sacrifice of one's own desires for the good of self and others. Montessori education, developed in this historical period, reflects this emphasis on the formation of the child's character. However, parents today are more likely to say their primary wish for their children is that they be happy. In pursuit of this goal they indulge their children, often unconsciously, to a degree that is startling to previous generations. All parents need to remember that true happiness comes through having character and discipline, and living a life of meaningful contribution -- not by having and doing whatever you wish.
