Sorry, but I have to point out that the studies linking vit k shot to leukemia have been pretty well disproven. As for 1 in 10,000 babies who have liver disorders being the main ones at risk for vit k deficiency bleeding....it may be true that 1 in 10,000 babies have a liver disorder that makes them prone to blood clotting problems, that is only one risk factor. There are several risk factors, although I agree that it appears that very very few babies are at risk all in all. It is not something that I worry about--at all. But still, people DO need the facts in order to decide. And unfortunately the first fact is not so factual....and the second fact mentioned gives only a partial picture.
Interestingly enough, the incidence of vit k deficiency bleeding seems to vary regionally--as high as 1 in 2000 in some places, as few as 7 in 100,000 in others. There was a thread on this in the Birth Pros forum some months back, a handful of studies were noted. I guess it turns out that we just don't have that many hard and fast 'facts' about this problem! It is also true that vit k administration does not prevent hemorragic disease in all neonates anyway--just in enough that has become considered (medically) as a necessity.
