Prenatal care and pediatrician help?

It shouldn't matter what type of coverage you have when it comes to finding the right doctor for you. What you'll need to do is check with the hospital you want to deliver at and see what doctors are contracted with the hospital. I don't know how Medicaid works, but if they give out a list of doctors, you can check that list against the hospital's list. You can do the same with the pediatrician and then when you find a few that look good to you, you can call them and ask about scheduling a consultation to choose your health care provider. I must warn you that some doctors don't really do consultations anymore.
