gain we shall
find a hired nurse to whom this extremely difficult task may safely be
entrusted. In a number of cases with which I have had to deal, I have
recommended the mother to undertake the duty herself, because she seemed
to me the most trustworthy person available. But it is a very
regrettable fact that many mothers are altogether unwilling to make the
necessary sacrifice for their child's good; and most of them are quite
ready to believe that some woman whom they can hire for a few shillings
a night will perform the duty which they themselves as mothers have
renounced. Such lack of proper feeling is especially common among those
who belong to what are termed the upper classes of society--to the
aristocracy whether of birth or of wealth--whereas among the middle
classes I have found mothers far more ready to make the necessary
sacrifices.

In sexual education, the sexual perversions must receive especial
attention. I must first of all refer again to two matters, of which some
account has previously been given: the influencing of congenital inborn
tendencies; and the undifferentiated sexual impulse. As regards the
former, we have to take the following data into consideration. The fact
that the indications lead us to believe that a particular sexual
perversion is inborn, need not induce us to think there is no hope of
counteracting this perversion by well-planned educational influences. I
have already written at considerable length about the undifferentiated
sexual impulse, and have shown that perverse manifestations during the
period of the undifferentiated sexual impulse do not prove that a
permanent perversion has developed. But everything possible should be
done to guard against the further development of any such perverse mode
of sexual sensibility, including sexual qualities in the wider sense of
the term. We know, for example, that many homosexual men have a tendency
to dress in girls' clothing, and many homosexual women to go about in
men's clothing, and, in both cases, to adopt the inclinations and
occupations of the opposite sex. During the period of the
undifferentiated sexual impulse, we must not attach too much importance
to the appearance of inclinations of this kind; but it would be equally
erroneous to ignore them altogether. Boys who adopt a girlish behaviour,
should not be encouraged in doing so by treating the matter as a joke.
If a boy frequently dresses up as a girl, or a girl as a boy, and i
