I just wanted to share that a few years ago I served an Indian couple who observed fasting as part of their religious practice, and even though she was "technically" not required to fast because of the pregnancy, she chose to do so (this wasn't helpful when it coincided with a long labor). I only share in order to say that sometimes individuals will interpret the teachings of their church in a way that you as their midwife may not anticipate. I believe I will try to do better to learn about such self-imposed requirements among my clients in the future as a result of this experience.
Thank you to all who posted here, as it is a wonderful resource.
