From the third month on to the end of the nine months, the amount of material which the mother must provide for the development of the child within her womb amounts to no small draft on her physical resources. It is not at all uncommon for a mother in the later months of pregnancy to become quite pale, her blood having been impoverished to provide material for the development of her child. MATERNITY. What has been said above regarding the contributions which the maternal organism must make toward the development of the offspring must have impressed on the mind of the reader that _maternity means, first of all, sacrifice_. This sacrifice begins when the girl first enters upon womanhood. With the expulsion of the ripened ovum comes, each month, a week of special physical drain, when work must be lightened and vigorous exercise curtailed, when exposure to cold or dampness may mean loss of health. Under these circumstances a woman should at this time deny herself the pleasure of dancing; of skating or swimming; of sleigh-rides or cross-country walks and the young man should make it less difficult for her by acquiescing without question or demur in her request to be excused from such recreation. It is a fact that more sacrifice is involved in maternity among the more highly cultivated nations of the human race than is true of aboriginal peoples, or among the lower animals. Conditions of modern life, and particularly urban life, leave the female organism less able to endure the drafts made upon the system by maternity, so that to bear a child may mean not only the sacrifice of comfort, but even the sacrifice of health. The highly sensitive, delicately adjusted nervous system of the woman is perhaps more profoundly influenced than any other part of her being. This manifests itself particularly in a heightened degree of sensitiveness. It goes without saying that the pregnant woman deserves at the hands of all who come in contact with her, and particularly at the hands of her husband, most considerate and sympathetic treatment. Her little whims and vagaries, however unreasonable, must always be treated seriously, and with delicate and tactful consideration. The members of her family, particularly the husband, owe it to her and to her child to keep her in as happy a frame of mind as possible. When we consider the real significance of maternity to the race, to society, and to the family, we must feel that, of all human relations, maternity is the most sacred, and that no condition should be allowed to mar it, and no consideration to take precedence of it.
