Isn't Vit K given IM at birth to provide baby with a supply until baby's
body starts to naturally make enough of own Vit K in the gut, around day 8
(when Jewish babies are traditionally circumcized)?  Our current use of Vit
K is based on the knowledge that a newborn has low levels until Vit K is
made by baby's gut- flora in gut develop after feeding and make K.  So what
if baby's Vit K level at 2-3 mo is 1/2 of adults, maybe that's the design
plan.  As a Pediatric nurse practitioner I don't want to have to give "one
more shot" to a baby just because he's bestfed! Pat in rainy southern NJ
