Up on all fours!

Last night over at my Cousins for dinner, Coy and Tristan were playing on their mat and Coy decide to get up on all fours as if he were about to crawl. He knew this was exciting, but he didn't knwo what to do next. So he just kinda hung out there looking at Tristan as if to say"look, here is how you do it." He should be crawling soon.
So later when we got home we put him in his walker and he traveled through the whole house. It was a great night!
