(not speaking from a midwives point of view) A good friend of mine free birthed her DS. She knew she had super fast labours and was 200kms from the nearest birthing hospital (other hospital near by) she woke up at 3am as she felt like she needed to poo and within a minute her DS was out. By the time her partner woke from his sleep bubs head was out and he had time to roll over and catch his body all of a minute from the time my friend got out of bed. Her son was born at the side of the bed whilst she was standing. As he (Daddy) was not expecting it and the slippery little bubba was hard to hold he sort of fell to the floor and the weight of him split the placenta in half so half was torn away and the other half not detached. My friend lost a lot of blood well over 2litres which required a blood transfusion at the hospital nearby before been transferred to the main hospital. I think if it didn't happen the way it did there wouldn't have been a problem with blood loss. Just one of those things.
