Parents and teachers must see that children learn good habits and attitudes in their formative years. What is read from books must be contemplated upon and reflected upon in silence and quietness. This is a very good exercise in intellectual development and in the acquisition of mental peace. The instinct to quarrel and fight over any and all misunderstandings must be regulated and sublimated. You should not cause children to suffer mental anguish or physical pain! Children also should not enjoy the infliction of pain on any being. They must be brought up with a sense of responsibility. They should be taught not to take delight in showing off their dress, ornaments, status or wealth before the less fortunate. They must be taught from early on, habits of personal cleanliness and most importantly, the habit of prayer at regular hours.(Divine Discourse, Sep 3, 1958.)
