When Sarah Toyer discovered she was pregnant for the fourth time, she was determined to have a maternal-assisted C-section.

And that she did, with the now-mum-of-four welcoming her son Spencer to the world with her own hands by pulling him out of her womb and on to her chest.

Reported by Yahoo Style!, Sarah took to Facebook to tell share her incredible story on the page Birth Without Fear.

The jovial mum wrote, “When I discovered I was pregnant I was determined to have a maternal assisted C-section. I talked to every midwife, doctor, and surgeon about what I wanted to do, but they all said it would depend on the surgeon on call that day.”

“So, when the day came along we waited 8 hours at the hospital, then I was standing there next to the surgeon scrubbing up just as she was. Maybe half an hour later, I was lying on the operating table watching my son's head being pulled from my womb.”

“I reached down and put my hands under his arms and lifted the rest of him out of my own body. It was the most incredible thing I have ever done.”

“Welcome earth side, baby Spencer."

Ms Toyer then used this post to encourage women to strive to have the birth that they desire.

“I highly recommend you stick to your guns about what birth you want!
