Hygiene of Pregnancy.-- The health and perfection of the child depend largely upon the health and perfection of the parents at the time of its conception, as well as upon the condition of the mother during the pregnancy. Even when both parents possess a strong constitution, but one or both of them is suffering from a temporary exhaustion or malaise, the child will be born below the standard of health it ought to possess. Children born during the first year of married life seldom equal in health the children born of the same parents later; they are not only apt to be sickly, but the liability to premature death is greatly increased. For this reason it is better that the first year of married life should be allowed to pass without conception taking place. A child begotten in an intoxicated or depraved condition of a parent may be depraved itself in the same way, and is apt to be feeble-minded or idiotic. It must be borne in mind that prenatal culture of some sort begins at the time of conception; and that on the mental as well as on the physical state of the mother, the health as well as the disposition of the child will depend to no slight extent. The prospective mother who constantly gives way to her feelings does a wrong to her unborn child. The mother is at this time more impressionable, more nervous, and more irritable than is natural to her; and while her family should make a certain allowance for her condition, she, on her part, should not allow herself to give way to her morbid feelings. The prospective mother should not lead a life of self-indulgence, on the one hand, or, on the other, should not be weighed down with cares; she should interest herself in her usual duties, and be relieved of all anxiety possible. Dress.-- The clothing must be loose, and all compression about the waist and abdomen must be especially avoided. If the woman wears corsets, she must take them off at once, and substitute a Ferris or some similar hygienic waist. The corset prevents the proper development of the abdominal muscles, which play so important a role in the expulsion of the child from the womb, as well as in the proper growth and development of the fetus itself. If the woman has already borne children, and toward the end of the pregnancy the abdomen becomes pendulous, she will very materially add to her comfort by swearing a muslin abdominal bandage.
