They say what sometimes you can't say... if that makes sense. At the time of giving birth sometimes it's a bit hard to say things - which is where your birthing partner comes in and having what you do and don't want in writing can help them also... just remember to be flexible if need be. I actually didn't really have much of a chance to use mine as everything happened in 3 1/2 hours and less than an hour from getting to the hospital. Although having said that I had already mentioned during visits that I was hypnobirthing so they had that written on my chart already. I didn't want intervention but had to have vacuum due to baby in distress, but we made that as an informed decision at the time. Hope some of this helps you and happy birthing!!
