Yes. I remember scoffing when my grandmother, who raised 11 children, tried to warn me that I wouldn't have as much control as I envisioned early on. Most of us seriously overestimate the amount of influence that parents have.

By the time you get to 3, it's pretty evident that each child comes pre-built with their own unique tour-de-force of personality, and parents are just as beholden to it as anyone else.
