Research and study are the hallmark of well educated parents. The following links are good starting points on decisions you will be faced with throughout your pregnancy,birth and parenting days. I always like to include resources from the midwifery model of care & natural approach to the mainstream standard of care so that you can decide where your beliefs fall on these topics.
For a myriad of birth related topics that are well researched and explained for the lay person in mind :
Group B Strep
Rhogam injection for Blood Type Negative Mothers
VBAC _ Vaginal Birth After Cesarean
Vitamin K-For the Newborn
Erythromycin Eye Ointment-For the Newborn
For those choosing circumcision I highly recommend "The Rabbi"
Rabbi Michael Rovinski The Rabbi offers a reduced rate to midwifery clients.
