27 breastfeeding mothers and 9 non-breastfeeding postpartum comparison mothers in Bangkok, Thailand were followed longitudinally until ovulation resumed. A simple set of guidelines is described involving 3 obvious milestones for the breastfeeding mother to safely use the natural contraceptive benefit of breastfeeding. Those milestones are the 1st menses, the initiation of supplementation and the child's monthly birthday. In the absence of menses and supplementation, 93% of breastfeeding mothers remained anovular for 3 months postpartum and 88- 89% for up to 6 months. Further, the work of other investigators suggests that the proportion ovulatory provides an overestimate of those at risk of pregnancy. These guidelines may be useful to mothers to help them utilize family planning services to their advantage. They will help in estimating the period of lactational infertility. Future studies will determine if the guidelines are understandable and acceptable to breastfeeding mothers and family planning workers. (Author's Modified).
