Hi everyone,
  I didn't see the original post on vitamin so this may already have
been said but, my understanding is that vitamin K has to do with blood clotting
and that it comes in naturlly in babies over the first week.  It is given
in the form of injection in many (if not all) of our local hospitals
here in Boston in the first 24 hours.
  I believe that there was a study reported i Lancet a few years ago
claiming a possible corrlation between vit k injections and pediatric
cancer. I don't have the reference and I don't know if follow up
studies have been done.
  Has anyone asked the question why vit k doesn't come in for the first few
days of life and if it soes in in lower levels or more slowly for
breastfed babies, maybe there is a reason for that! Does anyone know what
are the chances of a newborn having internal bleeding in the first few
days of life and what are the factors that make that more likely.
  I guess I am one of those who likes to begin with the assumption that
mother nature knows what whe's doing better than we do and we should be
careful before we second guess her.
