Sorry if I've forgotten if I introduced, I'm Kathy in VA, LLLL for going on 9 years. I remember a terrific Breastfeeding Education Workshop in Phoenix and the morning topic was physiology. It has always stuck in my brain that the breast develops the "stuff" to lactate a little at a time. I have all along thought with each menstrual period, more aveoli develop........and so (here's the question) if a 15 yr old (and I would take into consideration girls "seem" to be getting younger for onset) has had, for instance, 10 periods, she would have more chances of BF successfully than a 13 year old who has had 6 periods? . And, yes, I wholeheartedly agree with the idea that many teen mothers are too distracted to focus on mothering and that is what causes "failure". Any thoughts?
