Mommy knows worst

This is just a small excerpt from this funny yet troublesome book that I received for Christmas...(remember this book contains ACTUAL ads and articles from the 1950s that were suppose to be the best and most accurate advice for parents at the time)
"Baby's Sleep; Ordinarily he should be taken up only to be fed, bathed, or changed. Many people seem to think that a baby is a toy provided for the amusement of relatives and friends, and do not scruple to interfere with his very important business of growing up whenever they want to entertain or be entertained. In other words, it is considered perfectly proper to take him from his crib at any time when he is not sleeping for the purpose of exhibiting him, kissing, cuddling and bouncing him about.
This practice is a very pernicious one. The mother, perhaps, cannot be denied altogether the privilege of exhibiting her child to admiring friends, or of taking him up in order that she may lavish upon him her own caresses; but such disturbances should be reduced to a minimum, for they are very trying to the child's nerves and may even cause direct injury to his delicate little organs.
Still another harmful result may be to start the child in life with an exaggerated idea of his own importance. If his own common sense does not correct this error later on, it is not too much to say that it may land him eventually in an insane asylum, for the "exalted ego" is the most common delusion of the insane, and frequently has its origin in the first few years of the demented one's life. The Japanese are exceptionally free from this delusion. This is due to the fact that they do not pamper their infants. The early years are the most impressionable, and only too often infants are led astray with wrong impressions."
We cannot emphasize this enough; Leave the child alone. Is it crying? No. Is it soaking wet, or are its buttocks caked with its own abominable filth? no. Leave it be. If you pick the child up and kiss it, there are two possible outcomes;
1. Internal organ damage caused by rough gusty "Bronx Cheers" on the belly: spleen ruptures from a "harmless" game of gitchee-gitchee-goo.
2. Insanity, commitment, and the necessity of the parents staying indoors with the shades drawn for the rest of their lives, out of the decent sense of shame. When in doubt, remember: nothing shreds a child's nerves like a mother's disturbing caresses.

How did Dick and Jane ever survive (let alone poor spot if they treated their children this way..imagine how they treated their pets!)?
