Becki, do you have a pedeatrician? just go to them if you are happy with that doctor? we do all our jabs at our local medical center (costs an absolute fortune, get ready! hope your insurance covers it) - for example we had 3 jabs (ok, we have twins but still...) - was $4,750... nearly had a heart attack
you can also use the public system which is very good (and VERY CHEAP) - I remember it cost $10 to register 3 years ago when I had my daughter - and after that all the jabs were free. There are two or three that aren't offered on the public system (Hib and Pneumoccocal I think) and these you can get at any local pediatrician and pay the fees for shots there.
