I've (hopefully) got months before I have to put this into practice, but I was just thinking about jotting down some notes for my birth plan.
WIth DD I did push when I felt like I needed to (I just didn't tell anyone) but I know you aren't supposed to until they tell you to.
But surely you should just trust your body to do what it needs to?
What is the science behind the idea that you shouldn't push?
