I have seen quite a few women experience menstruation at or even before 6 months pp. Most of the time, in my experience, these have been either young women, under 25, or women who may have been obese. Both of these appear to have higher estrogen levels, thus even with Enviromental Breastfeeding, menses can return earlier than some expect. I don't automatically assume they aren't breastfeeding "properly" as I have seen this *too* many times, in women who are breastfeeding quite often, and not supplementing. Even some older women with normal body weight may have higher estrogen levels, thus causing menses to return before the 12 month mark.
