A little over a month ago, I wrote a post about using breastfeeding as birth control. I got a lot of comments. Many people were confused, some had heard a different comments from their doctors, and others shared experiences where this method of birth control didn’t work.
So, I want to use this post to clarify…for most women,bBreastfeeding provides a natural delay in women’s return to fertility.
The biggest effect of breastfeeding on menstrual cycles is seen in women who practice what is known as ecological breastfeeding. These are the seven requirements of ecological breastfeeding are:
- Exclusive breastfeeding (no other liquid or solid from any other source enters the infant’s mouth) for the first six months of life.
- Comfort your baby at the breast.
- Don’t use bottles and pacifiers.
- Share sleep with your baby for night feedings.
- Share sleep with your baby for daily nap feedings.
- Nurse frequently day and night and avoid schedules.
- Avoid any practice that restricts nursing or separates you from your baby.

In order to achieve ecological breastfeeding, you have to meet ALL of these requirements. Not just one. Not just two. But ALL of them. Mothers who breastfeed but don’t do so exclusively (or don’t follow all the recommendations of ecological breastfeeding) may have delay in the return of their cycles, but usually not for as long of a period of time as mothers who ecologically breastfeed.
Researchers at Georgetown University developed the Lactational Amenorrhea Method (LAM) of birth control to quantify exactly under what circumstances breastfeeding is sufficient birth control. As long as the three conditions of LAM are in place, the chances of pregnancy are less than two percent, making it a more reliable birth-spacing method than a condom or a diaphragm. The conditions for the effective use of LAM are:
- Baby is less than six months old.
- The mother’s period has not yet returned.
- Baby is exclusively breastfed (with no pacifiers, supplemental bottles, or solid foods) and nurses on demand both day and night.

Did you doctor tell you breastfeeding isn’t an effective form of birth control? I would say it’s probably because most doctors don’t teach ecological breastfeeding. Did you get pregnant while breastfeeding? It was probably because you didn’t meet all of the conditions mentioned above.
Please keep in mind that timing for the return to fertility varies greatly from woman to woman and depends upon baby’s nursing pattern and how sensitive mom’s body is to the hormones involved in lactation.
And I just had to share this most recent picture of Kolt and I…still breastfeeding at 17 months!
There is just nothing quite like it.

That picture is so sweet!! I love the hands together!
And thank you so much for this post! I had no idea breastfeeding could be 98% effective if you followed all of those things. It’s interesting…I got my period back at around 8 months with Baby T (was working full time and pumping every 3 hours but nursing a lot at night), and I still haven’t gotten my period back at 12.5 months with Little M. At maybe 6 months and then at 11 months, I spotted when I was away from him and didn’t nurse for 6-7 hours, but I was just away from him yesterday and today for more than 6 hours without nursing, and no spotting. Wow. I like being period-free!
