HappyMummy,
That's the term i found while googling. It's the most natural context of breastfeeding. In short, it's about feeding your baby on demand, no mixture of anything at all, no EBM and nursing at nights. If one breastfeeds like that, they can experience amenorrhea (no menses) for as long as they BF. It's how they do it on the olden days before formula milk was ever invented. I wonder if there's women who exclusively breastfeed for a very long time, no solids no water no partial FM whatsoever in this modern age. Really salute this kind of mommy lor.
