I don't know if Kathy Slone and Associates (midwives) would be able to deliver your baby, but it would be worth it to schedule a consult with one of them. ( I think its 410-235-0506)
They would be able to refer you to someone that would be able to help you. Depending on your circumstances, they might even refer you to Dr. Robert Atlas, who is the head of OB/GYN at Mercy. for the head of a hospital delivery unit, he is very pro natural birth. One of the posters here went to him to turn a breech before a homebirth, and was pretty impressed-- he had absolutely no problem with her having a homebirth, which is strikes me as unusual for a hospital based doctor. I've seen him, too, for care of a miscarriage that was taking way too long to clean up, and he is definetly "low-intervention" style! You can only be seen by him via referral, as he specializes in high risk.
