ohhh i want to know about this too... i am sure it would help for the mother but i heard babies can't produce vitk is that right??? i also heard many ppl say that u only need the vitk injection if the baby has a difficult birth like ventouse or forceps coz that can cause bruising??? i also know that there is an oral dose if u don't like the injection idea.. dunno if this helps u at all hope someone will have some better advice for both of us
