That is, a failure rate of only a few percent (3 or 4% if I recall correctly) is achieved. Specifically, these mothers do not normally ovulate effectively before the first post-birth menstruation, so that the first menstruation would be a fairly reliable warning to start using other protection. (3) this failure rate (which is NOT zero), is as good as or better than the alternatives in the less affluent countries of the world. So the world trend away from breast feeding to using bottles is unfortunate.
