I think you have me confused with another poster

I never said blankets = germ protection
I come from a family of scientists and engineers (I'm the black sheep who went to law school). I have picked up a few things about microbiology from my parents (one is highly published in the field).
So I think that a blanket can deter other people from touching a baby. My suggestion is to avoid an airport and airplanes with a newborn.
