They know they are facing a big change and are concerned about how it will affect them. While we can't know the future, we can deal with the uncertainty that accompanies it. Asking a well-chosen daily question can help transitions feel less threatening, more normal. In my classes I don't lecture about the anatomy and physiology of labor. I know that the intellect is not what controls the birth process.
People already know how to give birth, anyway.
My job is to help them access the place inside where their birth knowledge is stored. I guide these parents to find meaningful questions to ask themselves every day. Although I teach Finding Your Question in birth preparation classes, it can be used by anyone to successfully navigate life. By following this procedure you can find your own question about a challenge you may be facing. It's the first night of class.
