Parents in today's world usually accept the fact that they should answer frankly questions from young children concerning procreation, birth, and the difference between boys and girls. These questions, however, make many a parent uneasy. Parents worry lest they say too much, or not enough; they worry if children are too curious, or if they fail to ask the right questions. Parents quite often ask for help from their pediatricians as to how best to carry out their responsibilities in the difficult area of sex education.
