What hell? They have all the power. At a different hospital than the previous one I mentioned, they called CPS on me for breastfeeding! That's how crazy they can get when you don't follow their policies. : Thankfully, the CPS director had breastfed all three of her children or else who knows what might have happened to my baby.
Also, my advice is to request a copy of the hospital policy. Lots of things they say are policy -- are not. They just say they are so you will give permission to do whatever. There are women in our community that believe the hospital I go too do not do VBACs and were told it was policy -- its a certain practices policy, not that of the hospital. The hospital teaches a VBAC class and do quite a number of them.
