Well obviously the first thing you can do when choosing the perfect obstetrician is to see if you can have the same one as your mother, since he knows your hereditary history and quite possibly helped her deliver you. That is of course the ideal case, and not many of us have the fortune to be able to go to the same doctor after we grow up, perhaps move away from home.
So that is one thing you should try to look for if possible. In case that isnt an option for you, it is highly recommended that you bring your medical history to your current doctor in order to keep him or her up to date with your evolution, especially if there are things that could affect a future baby. That being said, another important point to lookout for is the compatibility between you and the doctor: if things go well and you manage to go to a number of yearly consultations that turn out to be quite satisfactory, and you feel like the doctor understands your needs, you could think about the opportunity of making use of his services when giving birth.
With this in mind, you ought to enquire as well about the hospital where he performs the operations, if he performs them or he only deals with natural births, or if that is your option, if he can work with emergency labour: its not nice to think about these things but its relevant for a detailed medical and healthy birth plan to be able to count on your doctor. If its not the case, the best bet is to ask him if he can recommend someone that performs emergency labours, as these are more common that you think, and its best to be prepared.
If you dont feel happy with your doctor and you feel like he doesnt exactly get your needs, the best thing to do is to try and find another one that makes you comfortable in your skin and choosing one of the best Chicago OBGYN would be the best choice.
