Here are a couple of great books for you:
"Vaccinations: A Thoughtful Parent's Guide" by Aviva Romm
"The Vaccine Book" by Robert Sears
We are non-vaccinating at the moment and have had great results - our child is healthier than most and has waaayyy fewer illnesses than vaccinated kids at our church. We are focussing on diet and breastfeeding.
Japan has one of the lowest infant mortality - and they don't start vaccines till 1 year of age.
I would advise doing your research, making a decision, and sticking to it. Most peds will not agree with a delayed- or non-vaccinating strategy. The best thing to do is just to call their office and ask point blank if they accept non-vaccinating patients. That will save you a lot of time in interviews.
Good job for thinking it through!
Blessings!
