What do you do when you're fed up?

When Cannon gets fed up with trying to crawl he has been known to pose for the camera (and no, I did not prop him up like this) . . .

. . . get some help from Daddy . . .

. . . which sometimes backfires . . .

. . . take his agression out on things that can be chewed . . .

. . .  flail and make weird faces . . .

. . .  or just take a rest.
