I am working on writing up a birth plan, per my OB's request even! I want to be thorough without going over the top. I know a lot (if not all) of you have written up a birth plan at some point and I am hoping that you are willing to share some pointers or key things that you felt were important. What is absolutely necessary and what is more flexible in your view? I won't complain if you share your complete birth plan, or just share some ideas.
