This is one of the reasons why young wives often fail to have children. They "get rid" of the first one or two, because they are not ready to have children, or because they want some enjoyment themselves before they are tied down with a family. Having established the habit their womb has been educated to abort, and it will keep this habit up, much to their astonishment and chagrin. Young wives should therefore faithfully follow out all the rules of the Hygiene of Pregnancy laid down by their physician, and which are given in detail in this book.

The Taylor crib is probably the handiest and best one on the market.
