Among the best authorities, both men and women, in all the countries where this matter is attracting attention, there seems now to be unanimity of opinion in favor of the elementary facts of the baby's relationship to its mother being explained to the child by the mother as soon as the child begins to ask questions. Thus in Germany Moll has repeatedly argued in this sense; he insists that sexual enlightenment should be mainly a private and individual matter; that in schools there should be no general and personal warnings about masturbation, etc. (though at a later age he approves of instruction in regard to venereal diseases), but that the mother is the proper person to impart intimate knowledge to the child, and that any age is suitable for the commencement of such enlightenment, provided it is put into a form fitted for the age (Moll, op. cit., p. 264). At the Mannheim meeting of the Congress of the German Society for Combating Venereal Disease, when the question of sexual enlightenment formed the sole subject of discussion, the opinion in favor of early teaching by the mother prevailed. "It is the mother who must, in the first place, be made responsible for the child's clear understanding of sexual things, so often lacking," said Frau Krukenberg ("Die Aufgabe der Mutter," _Sexualpädagogik_, p. 13), while Max Enderlin, a teacher, said on the same occasion ("Die Sexuelle Frage in die Volksschule," id., p. 35): "It is the mother who has to give the child his first explanations, for it is to his mother that he first naturally comes with his questions." In England, Canon Lyttelton, who is distinguished among the heads of public schools not least by his clear and admirable statements on these questions, states (_Mothers and Sons_, p. 99) that the mother's part in the sexual enlightenment and sexual guardianship of her son is of paramount importance, and should begin at the earliest years. J.H. Badley, another schoolmaster ("The Sex Difficulty," _Broad Views_, June, 1904), also states that the mother's part comes first. Northcote (_Christianity and Sex Problems_, p. 25) believes that the duty of the parents is primary in this matter, the family doctor and the schoolmaster coming in at a later stage. In America, Dr. Mary Wood Allen, who occupies a prominent and influential position in women's social movements, urges (in _Child-Confidence Rewarded_, and other pamphlets) that a mother should begin to tell her child these things as soon as he begins to ask questions, the age of four not being too young, and explains how this may be done, giving examples of its happy results in promoting a sweet confidence between the child and his mother.
