Edit: sorry for being needlessly combative. > Very small kids have diapers. Planes have bathrooms. I have a 5 and 9 year old and fly regularly. I don't know if you've considered the amount of time that can elapse from seat belt sign on for landing to deplaning. Nevermind a turbulent flight. And trying to use the bathroom at the rear of a plane that just arrived isn't really going to smooth the deplaning process. But like I said, my family is not slowing anyone down, we're usually faster because we're ready and the adults organized the kids while we waited for our turn.
