Around 3hrs with the first, but only 5-10 min with the rest of them. I think that's pretty common to push really long with the first and a lot less with later babies. But some women have a long or short pushing stage regardless of what number baby it is. I think it's important to remember that averages are just averages and we're all very different. There's no right or wrong here. With #1 I felt like I was somehow less "good at" birthing b/c some of my friends only pushed 20 min w/ baby #1. But I realize now that's stupid. It's good to *hear* about other mamas experiences but it's not good to compare ourselves by any value judgement, ykwim.
Four hours with my firsts and only so far. That is a long time to push, and I was on the verge on a hospital transfer. I guess I was only "effectively" for 3 hours. It was really hard, but the time flies, and it was still a wonderful birth. Hope the next is easier! Hope yours goes smoothly.
