It can be said that a child is in the stage described in John Paul II’s words as ‘the years of innocence’ from about five years of age until puberty – the beginning of which can be set at the first signs of changes in the boy or girl’s body (the visible effect of an increased production of sexual hormones). This period of tranquility and serenity must never be disturbed by unnecessary information about sex. During those years, before any physical sexual development is evident, it is normal for the child’s interests to turn to other aspects of life. The rudimentary instinctive sexuality of very small children has disappeared. Boys and girls of this age are not particularly interested in sexual problems, and they prefer to associate with children of their own sex. So as not to disturb this important natural phase of growth, parents will recognize that prudent formation in chaste love during this period should be indirect, in preparation for puberty, when direct in formation will be necessary.
