There are mothers who take great care of their daughters' health [and appearance...] but little of their conscience. Far from forbidding them foolish and even bad books, indecent dresses, undesirable friends, indecent pictures, plays [movies], and dances [and immodest, unladylike sports], they allow them these things and even sometimes force them on their children.
Do not such parents know that spiritual fornication is a crime among Christians; that a look may kill a soul and that a desire or thought is enough to rob children of innocence and grace? [emphasis mine...pretty important point!]
Some mothers think that when they have brought a child into the world they have no further duty toward it. They hand it over to a nurse [or daycare] who may pass on her own bad inclinations to the child with the milk which nourishes it. From the hands of a nurse the child passes into those of a governess or tutor [or worse, a public or Catholic school!], who has perhaps been chosen without the parents' knowing if the person is good or bad! [I don't think the background check covers that - even in Catholic schools]
Yet marriage was instituted and is blessed only that children may be brought up in the fear of God. If only parents would take the trouble, what could they not do for their children!" [of course, this assumes parents are first open to life, and then actually open to parenting!]
