TrickyTeenagersMum said "Childbirth is not that big a deal, it's just something you have to do to get the baby out. If you come out wioth a live baby and in one piece yourself, then surely that is a good - or good enough - birth - by definition."
That's really not true though. For many, many women, how they give birth affects them for life. Often, women remember more details about the births of their children than they do about their wedding day or other special days. It can be a defining moment for many women when they face the greatest pain of their lives and find their body can do something it has never done before.
Birth trauma is horrendous and can have very long term effects. It is often linked to fear and isolation during birth, a sense that a woman wasn't cared for adequately, wasn't listened to or was violated. It can lead to post traumatic stress disorder and postnatal depression and can cause long term depression and anxiety. This is without even considering the long term physical effects.
On the other side of the coin, a great birth experience can be elating and empowering. It may be your experience that it's 'all in a day's work' but for other women, it can be life altering for better or worse.
For this reason, I support the OP to birth however she chooses and that choice should never be hindered by law.
But I would beg her to make sure it is a truly informed choice. I wouldn't consider birthing without a midwife. And there are lovely independent midwives out there who will work with you, or hover in the background just in case they are needed.
Someone asked why vaginal examinations might be refused in labour? Answer: Because they hurt, they're intrusive, they can encourage infection and because they don't tell you all that much you don't already know.
