I have done coached pushing and natural pushing. All three times, I *needed* to push, but with natural pushing I did it less and I never held my breath for more than a second or two. I was never able to "breathe" my baby out though. It hits me like a freight train, that desire to bare down with what my body is doing. I hated it when people would say "now stop pushing" or "don't push yet". Uh, yeah. How was I supposed to do that? It was beyond my control completely!
