I'm not gaga, nfk and I did it. Newborn babies' stomachs are tiny, 2 hourly feeding is absolutely normal as far as the baby 's needs are concerned. The interval between feeds increases as they grow and their stomach capacity increases. Most people get round this by having the baby in bed with them (not much approved of officially), or very close to them, so as to ensure minimum disruption for night feeds.
I know exactly what it's like to be in a zombie state through lack of sleep. It's the biggest shock to the system ever and something that one is utterly unprepared for. I also had a second baby who cried solidly and inconsolably for 3 or 4 hours every night, until about 1 or 2 in the morning, for her first 4 months and a toddler who woke at 5 a.m. It was survivable. But it meant letting go of every 'normal' activity and doing the barest minimum, childcare, meals and the washing, until that phase passed. Some women just can't let go to that extent.
I feel that you might be talking about a real and current situation. I've explained how milk production works; there's more detail here: emedicine.medscape.com/article/1835675-overview#a6 (scroll down to the section on lactogenisis).
But what it ultimately boils down to is what the mother is prepared to tolerate, how much support she gets, both expert and from her immediate family, and, what she feels is best for her and her baby.
Even breastfeeding for the first few weeks gives the baby a good start in life; no mother should ever be made to feel guilty if they feel that they just can't bear to carry on with it.
