I don't know about any of you guys but my experience with parenting thus far is that it is composed largely of fear.

First I was a terrified of my wife miscarrying. Then of the baby being stillborn. Then complications during the birth. And ever since my son was born it's just one concern after another, SIDs, sickness, is he developing at the right speed 

And now my wife is pregnant with our second is the same thing all over again. 

Is this common for people?
