B. G. Jefferis and J. L. Nichols, Searchlights on Health — Nursing (1919)
“ RETURN OF THE MENSES.—If the menses return while the mother is nursing, the child should at once be weaned, for the mother's milk no longer contains sufficient nourishment. In case the mother should become pregnant while the child is nursing it should at once be weaned, or serious results will follow to the health of the child. A mother's milk is no longer sufficiently rich to nourish the child or keep it in good health. ”
