You do have to look at it holistically and work out at what point it becomes your need to continue BF'ing through problems as opposed to her needing it kwim? I think there is a lot to be said for talking a that view of it - I can't see any point in battling every feed for god knows how long, just to be able to say you did it, when all that time you could have been enjoying every moment of newborn feeding instead of spending every waking moment dreading trying to get it to work. Because this stage is such a short period in their lives that you don't want to reflect back on it in years to come and only have bad memories kwim?
Brilliant point!
