I've never gone to a specific peadiatrician, just my GP who has plenty of kid experience. I figure if I needed anything more, he would refer me on to a paed.

As far as finding a GP, I guess I would call a few local medical centers and ask if they have a doctor who deals mainly with children and whether you can come in to meet them. There are actually some good lists out there of things to ask the GP at that meeting- I remember googling it before Peter was born and finding some good questions. I never actually did it, I just happened to totally luck out with the first GP I saw after Peter was born, but I don't think its an uncommon thing to go and interview doctors.
