Quoting Ryloonjimama:" Poll is pretty straight forward. I chose to word it this way, rather than *breastfed or didn't breastfeed* ... [snip!] ... do to build your supply up? Also, the D&D part of this, do you think that the birthing style plays a role in this issue?"
Vaginal. Both times I attempted to nurse, but I couldn't create a good supply with exclusively nursing so I failed the first time.
I think this poll doesn't really show the truth, because a LOT of women feel they didn't have a good supply when they actually did. They worry because the baby is fussy, or during a growth spurt, or the baby isn't sleeping as long as they think it should. All of these things can lead a woman to think it's a supply problem. Same with that some women supplement, then start to lose supply when it wasn't really a "supply" problem to begin with.
I think women who had csections have more hurdles to overcome. The pain and recovery is harder, which makes the breastfeeding more difficult, which means more "reasons" to quit.
