In the September issue of "Fertility and Sterility," the Word Health Organization agreed that the Lactational Amenorrhea Method (often called LAM) is an effective method of birth control.
The Lactational Amenorrhea Method uses three measures of a woman's fertility (the return of her menstrual period, her patterns of breastfeeding, and the time postpartum) to allow women to rely on breastfeeding as a family planning method.
A group of WHO researchers, led by Dr. Helena von Hertzen of the Task Force on Methods for the Natural Regulations of Fertility, concluded that, "The period of lactational amenorrhea is characterized by a profound degree of protection from pregnancy."
By studying more than 4,000 women in seven countries around the world, the researchers found that in the first six months postpartum, LAM is equivalent to the protection provided by most nonpermanent contraceptive methods. However, the pregnancy rate of women practicing LAM did increase between six and 12 months postpartum.
NO!! One of my very best friends was breastfeeding Baby #2 and was on was on a mild birth control pill that is safe to take during breast feeding....Baby #3 arrived within a year!
You need to talk to your Dr. about using breast feeding as birth control. S/he will give you the best advice. Breast feeding can be effective as b/c but only up until six months and only if your wife is solely breast feeding your baby (no supplements at all) and I think there needs to be certain time regulations~I don't know if it's every two hours or what? And I know you have to continue breast feeding into the night but I don't know how often. If your wife does not follow these rules strictly (or has not in the past) you need to find other methods of protection because she can and might ovulate. In addition to talking to your Dr., I think you can google it and find more information on the net. Make sure the internet site you look at is a scientific/medical site and not some average joe's opinion. Good Luck!
Lots of women don't have period during breast feeding, but that doesn't mean she is not ovulating....
She still need to take precaution, there are some birth control pills for nursing moms out there.
good luck...
