I think the majority of women, especially here in Hawai`i want a ‘natural childbirth’
The problem is the lines are being blurred as to what that is exactly, esp in a hospital setting
There are several techniques to use during childbirth, one of them being Lamaze, which is probably the most well known. Also the Bradley Method, hypnobirthing, using a water tub and using a doula.
Using these methods during childbirth especially in the hospital would help to lessen your need for medical intervention. The only way to have a significant chance of assuring an unmedicated birth is to have a homebirth.
Here are some descriptions:
