You have to be practicing EBF in order to use LAM, obviously. But...you can only safely use LAM for 6 months, but you can EBF for longer, right? So obviously they're not synonymous but I think when you're talking about birth control you could use them interchangeably and people would know what you mean, doncha think?
Oh, one thing about NFP vs FAM (besides what you mentioned, which I agree with). Isn't there something about the term "NFP" having certain connotations (i.e. that it's religious-based, that it's ineffective and outdated, that it's the same as the rhythm/calendar method, etc) that she wanted to avoid, so although it's basically the same in principle, she made up FAM to be a more modern term without the baggage attached to it?? Or something like that?
You mean you can EBF after 6 months as a method of BC? If so, what is the difference between the "rules" of LAM and EBF? Or do you mean you can EBF as a mothering choice (independent of BC) for longer than 6 months? Or... is it possible to get menses (so literally NOT amenorrhea) but still not fertile?! Also adding to the confusion, for me at least, is that I've seen EBF used to mean both extended breastfeeding an exclusive breastfeeding in addition to ecological breastfeeding.
I think you are right about religious connotations to NFP.
Great! Added your chart to OP.
