The use of breastfeeding as a contraceptive.

Breastfeeding generally is considered an ineffective method of birth control. Yet, in non-Western cultures breastfeeding has been shown to be a beneficial method for spacing births. The physiological effect of breastfeeding on ovulation, breastfeeding patterns that delay the return of ovulatory activity, and the practice of fertility awareness during the postpartum period are reviewed. Guidelines are suggested for assessing, teaching, and referring women desiring to use breastfeeding as a contraceptive method.
