Because new parents get freaked out by *everything*. Not to mention that no matter what decision you make, from feeding to what diapers you use to what color you paint the nursery, there is someone waving a "study" in your face to prove that you are about to permanently fuck up your child.

Luckily I didn't go through much of that. I spent a lot of my teen years babysitting and providing daycare for my cousins from birth onward, and had figured out that babies are far tougher than people give them credit for.
