I'm just South of TJ, but had my baby in SD, and work there too. I LOVE SD, but it's so expensive, even with a good income.
UCSD is very nice, Ive heard great things about their birth center. My pedi is in a UCSD practice (on Frost St) that is also a teaching group. I love it because you get so much extra attention and they are very thorough, plus the wait is never too long even though its crazy busy. I never get the feeling we are taking up too much time, even when I have a billion questions. My sons pedi is Dr. Pickering and he's great, very cute too, lol. I also see Dr Leff, she is also good, if DrP isn't available when I want an appointment.
For prenatal and birth, I had an OB, Dr Goldstein, who is in practice with a very good CNM named Sherri. I only saw her a few times though. He was fantastic, you could see either him or her for prenatal, your choice. I was very happy her was there for my CS, it would have been scary with a stranger. I had an amazing experience at Sharp Mary Birch, they are very kind and go out of their way to explain all procedures, as well as ask permission for every thing, from cleaning your bathroom to CS. DH and I were a little shocked at how great everyone was. the web says there aren't private rooms but this is not true. a few you have to share a bathroom, but not the room, but most are fully private. and everyone has full access to lactation nurses who are great. they are all about keeping baby with momma and BF.
If you arent going unmedicated, or think you may change your mind, they have the patient controlled epidural. This is awesome, you don't have to be crazy numb or immobile, YOU decide when and how much pain meds you want. They dont push pain meds at all either. Plus, they support all types of birth plans too. Unlike UCSD, they don't have a birthing center, they do have birth balls and such. it's the best place for high risk mommas and babies. My OB had a CNM as part of his practice, so I think they have MWs with privileges.
I wish I was a little closer, it's kind of a long drive for playdates or mommy nights out. it's a great city with lots of resources.
