We go to Peninsula Pediatrics (they are now in the Port Warwick area, off Jefferson Ave. (between Oyster Point and J. Clyde (17)). Our doc is always accepting new patients because, as one nurse told me, he can't say no. BUT, that means he's pretty full. We also see Dr. Baust there a lot because my daughter always seems to hit the wall of overwhelming sickness on our doc's day off. So, I can VERY HIGHLY recommend Dr. Baust, who I'm sure is accepting new patients, has children of his own (something I've come to appreciate) and a wonderful disposition. I don't think his patient load is too big, either, since he's the newest one to the group (maybe a year, now?). Anyway, you can call them at 8773-3334 if you want to check directions or new patient acceptance (or insurance, whatever). I think it's great you're looking for someone good - just make sure you're comfortable with what they say and how they say it, and you should be fine!
Good luck on the newborn!
