What is baby's first innoculation? At birth, the infant is exposed to a myriad of microbes from mother's vaginal canal, and this is important in building a foundation for baby's own gut flora and innoculating her. In utero, baby's digestive tract is void of important healthy bacteria that is needed after birth.
After reading many of my colleagues articles from the Weston Price Foundation (and beyond), I'm beginning to realize the importance of the gut! The process for our newborns takes approximately 20 days after birth, for this reason it would be ideal to give birth vaginally, without antibiotics and to breastfeed (no formula!).
If mom is unable to do the above, it would be ideal for her to begin probiotics for at least a month following birth.
