But I'm Not Sleepy

Wyatt has never been a fan of nap time.  And since he started crawling, as soon as I put him in his crib for a nap he pops up and does anything but sleep.  At some point he just falls asleep - if he was sitting up when he falls asleep he ends up sleeping slumped down over his legs like this.

And he was playing with his crib aquarium or yelling for help through the crib bars, this happens.
