Summary

B. G. Jefferis and J. L. Nichols Searchlights on Health — Words for Young Mothers (1919)

A rubber nipple shield to be put on at the time of nursing, is a great relief. If the nipples are retracted or drawn inward, they can be drawn out painlessly by filling a pint bottle with boiling water, emptying it and quickly applying the mouth over the nipple. As the air in the bottle cools, it condenses, leaving a vacuum and the nipple is pushed out by the air behind it.
