If bf is a task requiring an army of backup then when are we going to admit that for lots of women, it's really effing hard.
Also just to address this - child-rearing is a task that demands an army of back-up. It is intensive and consuming! And as we can observe in many other cultures, mothers are supported in this and not expected to manage it all on their own with some trifling input from a partner who is out to work most of the time. Even in our own culture mother and baby used to have a bit of 'lying in' together, women would have their mothers and sisters around them perinatally, there was a community. Nowadays we live so isolated from each other, when a woman has her own baby it can be the first time she has ever spent any significant amount of time WITH a baby. Women would once have had a week in hospital following a pretty uncomplicated birth; now women post surgery are supposed to ship out as soon as they can stand up and just get on with it. All of this is bloody hard.
Bottle feeding takes ONE aspect of this challenge away (feeding can be shared, no adjustment period while learning the skill that is breastfeeding required, normal infant feeding patterns can be overridden so newborns eat a lot infrequently rather than little and often).
But it also serves the 'just get on with it and act like you haven't even had a baby' culture we have in the UK, that insists women 'get their lives back' within days/weeks of giving birth instead of making any space or allowance for the fact their lives and bodies have completely changed. Maternity leave doesn't need to be extensive and well paid to accommodate breastfeeding, because you can 'just switch to formula/just pump' and get back to being economically productive.
All this can work for mothers who want that freedom and choice. But for those who want to sink deep into the motherverse, who want to be wrapped up in their child, feed them from the breast responsively, take time out from normal life to really privilege that life experience with time and attention - "you don't need to" becomes "you shouldn't" very easily.
I think it is fair to acknowledge breastfeeding is effing hard in the society and world we have created for ourselves. However, I think it is equally legitimate to question the sustainability of breastfeeding in that environment AND to question the environment that makes breastfeeding (an integral part of the mammalian experience) so effing hard.
