I don't disagree with anything in your last post, lela. But the problem is that it's HCPs who are telling women to suck it up when it hurts, what did they expect, that their babies can't possibly be getting enough milk, and the support just isn't there.
HCPs whose only answer is 'the latch must be wrong' when the problem is agonising refill pains, which went on for months.
Let's look at the bloody system and support available and focus on that, rather than on new individual mothers and whether their choice is acceptable or not. When the system is good, when qualified, effective, timely support and intervention exists, then it might, just, at the extreme, be ok to ask a woman why she gave up breastfeeding if she had originally planned to do it, so we can understand the other factors.
If I hadn't had the experience I had with DS1, I would have stopped feeding DS2 when he was 5 days old and the midwife told me he 'couldn't possibly' be getting enough milk in 5 minute feeds, he must be starving.
Then she weighed him, and he was a few ounces over his birth weight (of 10lb+). She didn't backtrack though, even when she saw him feeding with a latch so strong it left bruises.
