This makes me angry.

When a mother is not prepared for birth, but seeks a natural birth, the demands of their nurse are drastically increased. Nursing units are often understaffed and nurses are overworked. There is a tremendous demand on a nurse when a mother is not prepared for birth, a father is not prepared to be a birth coach, and a doula isn’t present to assist mom throughout the birth process. This can create animosity towards the patients that seek a natural birth, but due to lack of preparation rely on their nurse for all of their needs during labor. Even though more women are asking for a natural birth in the hospital, many still end up with unnecessary medical intervention due to their lack of being informed and prepared. Unfortunately, this means that even labor and delivery nurses lack experience in the natural birth process, because the majority of patients are not giving birth naturally. They also doubt the ability for women to birth naturally, because they see many unsuccessful attempts. When a well-prepared and well-informed mom comes in to the hospital, they are often faced with judgment and animosity because they are categorized with the moms who aren’t prepared and informed. They assume that they will be unsuccessful also.
"You come in and we laugh at your birth plan: you have a vague idea but haven't prepared, so when we push drugs and interventions you just accept them, cos you're more work if you don't just let us yank the baby out when we want. You need to bring an advocate (doula) in with you because we won't listen. And we use words like unsuccessful to describe your birth and further destroy your self-esteem when you had prepared and we just pooh-poohed you."

Pretty much sums it up.

Demand all you want - you still won't get to give birth if you approach a medical person about it.
