I don't know about MCA or Arlington Memorial. However, I don't think it would matter at all switching hospitals. I just had my little girl two weeks ago at Baylor All Saints and my OB did not deliver her. She came in the middle of the ice-storm and the on call doctor did the delivery. I definitely feel like we could have gone anywhere since I did not know the doctor or the nurses who cared for me. I had toured the facility but that was the only familiar thing. I would choose the hospital that will give you the best all around care including the baby. I was very impressed with All Saints and happy to have delivered her there. Not being familiar with the doctor wasn't an issue.
