Fatigue impairs the function of the milk glands. Women who are over-active in any type of activity, or who are overworked in factory, mill, store, or home will fail to nurse their children. One of the most outstanding evils of the modern industrial system is its destructive effects upon womanhood and motherhood. The exploitation of women in industry robs babies of the care and companionship of their mothers and robs them of their mother's milk so essential to normal development.
Mothers should receive sufficient rest and sleep to maintain a state of wellbeing at all times. Night nursing, that robs them of rest and sleep, also trends to reduce the milk supply. Night life, gay parties, theatre parties, etc., rob mothers of the ability to nurse their babies. Women who do not want to be mothers in the full sense should refrain from incurring the responsibilities of motherhood. They make better mistresses.
