I am taking 200 mcg of vit. k daily. I feel it is safer. The vit. k shot has been linked to Jaundice and even potentially white blood cell malformations and luekemia (those aren't proven, but it makes sense). I prefer to do the supplement. My daughter, Becka, was born and was jaundiced for a long time. She had both Vit. K shot, and the chord was cut immediately... so I am unsure which one caused it since both can. Taegen, who is 3 days old, has no jaundice at all. She had neither done :)
As for the silver nitrate. That's a no for me. While it *could* protect against potential infections besides those of the 3 STD's, it can also cause serious complications: a chance I wasn't willing to take.
But, Taegen was born at home so I didn't have to worry about any interventions lol.
