Bobby never once fell asleep in his high chair.
But when you're the second child...
... you're too busy trying to keep up with big bro to take a morning nap most of the time
... your mom's too busy trying to keep up with both of you to notice you're about to go down
... and henceforth you fall asleep during meals on a regular basis. (Or at least three times. Sometimes mom reaches in to save you just before you lose consciousness.)
Poor Owie Bowie.
