Like John Stossel says, "Gimme a Break!" With each pregnancy, I hear about birth plans and how useful they are. Sure, I filled it out a couple of times. When the day comes, it's thrown out the door. Everything is really spur-of-the-moment.
Some moms may find the plan useful, but I'm willing to bet not many stick with it or even bother to remember having it with them on the big day. I remember the most important things because I feel strongly about them.
On the other hand, if something should happen and the mom isn't alert -- then it is wise to notify someone of your wishes. I count on my spouse to handle that. If there is no spouse or partner, then documenting it would be wise.
My plan? Epidural - God, yes! Induce labor? Only if necessary. Anyone in the room? Just spouse, thankyouverymuch. We do let Mom in to be the camera manager. Monitoring - do what's necessary, it don't bug me none. Position - whatever feels right for the time. Enough, isn't it? This particular one is almost 12 pages! Mine fits on one page.
