Me! With my second baby, I did not push at all, and breathed the baby down! I tell people that and they look at me funny, so I was glad to see this question!
My first baby was posterior, and I pushed for an hour or so, and it was the hardest part of my labor. In fact, I don't remember much about that hour. During my second pregnancy, I took a Hypnobirthing class with a wonderful woman friend. I didn't start until close to the birth, actually just maybe a month before. I have to admit that I did not practice that much. She came to our home, and those sessions were very helpful. One of the most helpful things was when she explained to me the concept of not pushing. I had never heard this before! She suggested practicing while having a bowel movement, don't strain, practice breathing it out! Sounds crazy, but I am really glad I did that (I only did it once or twice, but it really helped me to understand the sensation and the process!!). Then when the time came, I really did not push at all, and it was so amazing. I truly felt each part of my baby's body as he came out and was born!
I highly recommend doing a class with a private instructor if you decide to check out Hypnobirthing. It made my second birth a very different experience!
