I still think it better to give the vitamin K intramuscularly.  I have
not heard of breast refusal after oral vitamin K, but we do not use
oral vitamin K here in Toronto.  They do in Halifax (Canada), but I
doubt they have more breast refusal than we do.

The question of IM vitamin K and leukemia is a red herring, unproved,
and really unlikely as far as I am concerned.

I have seen a baby bleed into his head, and it is terrible.  A baby
born after a midwife delivery at home, non traumatic.  Parents refused
vitamin K.  At 6 weeks, the baby was in intensive care.  The prognosis
for normal development is virtually zip, though I don't know what
happened to him in the long run.  Just one case?  Well, okay, but a
preventable tragedy. Actually I am aware of one other.
