K.S.
Raleigh has some very nice birthing centers, so you will be fine just about anywhere. I had my first baby at Rex and was more than thrilled with the nursing staff and amenities. My second child was born at WakeMed and I will have to say that I had an even better experience there just because of a better OB/Gyn and less stress/anxiety.
My OB is Kamm, McKenzie, Harden, Smith, Bass, Marston, Saacks, & White. I highly recommend them. They have two offices, one that is very near you on Falls Valley (at Falls of Neuse & 540). They only deliver at WakeMed these days, so if you are cool with that, they would be a good match for you.
Be sure to start your prenatal care asap. Best of luck with baby #3!
