Do any of you have experience with them? They were recommended to me by my primary care nurse practitioner after telling her that hubby and I want two very different types of birth. I would prefer a very "granola" situation--no meds, birth center, possible water birth, while hubs wants an OB/GYN and hospital. She said they are a good blend. One thing I am worried about is in scheduling my first appointment she said I wouldn't have an U/S of any kind until an anatomy scan at 20 weeks. How do they determine viability? This is my first pregnancy, so I might just be confused. Any insight would be awesome!
