According to my mother, there pretty much wasn't anything I wouldn't eat as a child. Not just try, but eat. I was even inclined to dig into stuff about which she expressed open disgust - lobster and other shellfish, and cheap Chinese food with pepper so hot it made your gums feel like a medieval dentist had been at them.
You want a child who never makes you anything but proud? Please. Don't bother taking on parenthood if you can't handle the fact that sometimes your child's identity won't be what you would have chosen. And if you want to prevent a child from ever suffering? Well, then don't have a child. No one is born into the world never to suffer.
