@ai6yr Thanks for sharing the article.
I find it reasonable of parents to be skeptical of the vitamin K shots. It seems logical that if babies were routinely born with a fatal shortage of vitamin K, evolution would have fixed that problem hundreds of thousands of years ago. If there is something about modern life that has made vitamin K deficiency a new problem, explain that to parents so that they will understand!
That's what responsible doctors do when parents are vaccine skeptics. It is simple to explain that our hunter-gatherer ancestors of 10,000 years ago didn't need vaccinations, because they lived in small bands of people and very seldom encountered germs from outside the band. Today, with most people living in large cities, and airplane travel spreading germs far and wide, vaccination against germs is essential for us in a way it wasn't for our distant ancestors.
If there's a similar explanation for why vitamin K shots were once unnecessary but now have become necessary, tell parents about it. Otherwise, it is reasonable for them to think that evolution would have eliminated a condition that affected a significant percentage of babies.
