Paranoia would be those who keep their children wrapped in some kind of germ-free bubble, where everything seems to have a kind of film of disinfectant. As Midnight Blue and chary have said, we need a little dirt!

It's pretty sad when parents are that extreme, because it can be detrimental rather than helpful or healthy.....I knew a woman who, with her first child, was so paranoid about cleanliness and the potential for allergies, that she had decided there should never be a dog or cat in the house for fear that her son will develop an allergy to them. Even though she loved cats and had owned them in the past, so it wasn't just a disinterest in pets in general.
I tried to tell her that I had read many things to the contrary, that research has in fact found that early exposure helps
prevent the development of such an allergy because a child's immune system puts its building blocks together in those first two years of life, based on what the child is exposed to -- the body is an amazing thing and can't learn to fight what it's not allowed to take on. She was a very intelligent and highly educated woman, so I was surprised that she hadn't come across this info about babies immune systems
