Cason's Almost Crawl
This kiddo is SO close to crawling it's unreal. Every day I expect him to wake up and scoot across the floor, but so far he's just doing his best rock back and forth. He's even perfected the seal flop, complete with high leg kicks and everything, only to find himself in the same place in which he started.
Here he's demonstrating the perfect form for rolling over. Tuck arms, hold hands, swing leg. He could teach a class on infant rolling.
