I pushed my first out in 11 minutes.9lb 1oz. He had no cone head.
Oh, and I did hynobirthing, but my BODY told me to push like a mofo. I think you'll know what you need when it happens. Some mamas need a little help or "coaching" while pushing. We're all different.
I think it's really variable on how long a mama pushes. I've seen some take 4 hours and others take 1 minute. We're all so different.
