I'm a homebirth midwife and I see natural births all the time. But when my own daughter-in-law was pregnant with my first grandchild last summer, I brought this video over so we could share it together. She loved it and we watched it more than once. We laughed together when I told her that I would try to remember tell her to "let herself become nice and juicy" as the narrator describes in her lovely Russian accent. And she said she wanted to be reminded to swirl her hips, as some of the women did in the video. Although she went 12 days overdue, she had a very efficient and successful home waterbirth in which she did indeed swirl her hips while pushing! And she told me later that she felt that watching this video really helped her prepare to surrender to her labor.
I have shared it with other moms too, and everyone thinks it's super. I've seen lots of birth videos, and believe me, this one is special.
