It's a vicious circle with mid centres, even homebirth - the fewer of them there are, the less normalised they are, the more nervous women are about using them. You offer the services, more people use them, and then it becomes more normalised and people want to use them more.

You just have to look at the demand at birthing centres to see how much in practice women want to use these services.
Too true. And you just have to look at how booked out our birth centres are to realise women do not actually have choice! They end up in the public system because the birth centres only take you if you found out you were pregnant yesterday. So many missing out on what they want.

At the end of the day it doesn't matter if only 10% wanted to use these services, the fact remains that there is not choice for women, and those 10/20/30 - whatever percent - deserve choice.
