BABY BOUNCING
The common custom of bouncing or trotting baby on the knee is a harmful one. The young and growing nervous system of the child is decidedly injured by this constant jolting and jiggling, to say nothing of the "spoiling" effects of this practice. There is a vast difference between the sensitive nervous system of the infant, with its liability to shock and disturbances, and that of the settled and developed nervous system of an adult. The strength of the mother or nurse is so great that the jarring not only often causes indigestion and vomiting in the infant, but sometimes also lays the foundation for "wrecked nerves" in later life.
The tossing of baby in the air comes in for the same condemnation. Baby is not "our plaything," and must not be bounced and tossed about like a rubber ball.
