We liked Dr H in Carver when we lived in West Plymouth and also have heard good things about Dr Griever in Halifax
Dr Harootunian in Carver (Plymouth Carver Pediatrics), he's a DO and family practice http://www.plymouthcarverprimarycare.com/ 508-866-7722
Some families go up to Norwell to see Circle of Life or to Harbor Medical in Pembroke - We currently use Circle of Life (husband wife team, also DO's).
Some people have liked Long Pond Pedi- but others have had problems with vax delays.
Some threads from the board here and I'm sure there are more:
If you can't find someone via searching here you could also try the local AP parenting groups....
or Holistic Moms Network https://www.facebook.com/HMNSShoreMA
BTW, most of the doctors including the ones above are pretty standard and will give you the AAP info and not AP information- but these pedi's have patients that are AP and they are supportive. Most doctors are not well versed in breastfeeding so parents should be aware of local resources for breastfeeding support (such as LLL and the hospital LC run support groups). So although these docs may start talking about solid foods around 4-5 months, if you know you want to continue breastfeeding longer, they will encourage and support that. It is frustrating that they base there care that way- but it seems to be the way it is since the majority of their clients are expecting that info.
