This is the first day Jonathan started to crawl for real (a few days after he turned 1) - on his hands and knees. He eventually falls and slips back into army crawling, but he's starting to figure it out!
Jonathan has done this a few times recently, and while his aim still leaves much to be desired, it's still fun that he enjoys throwing and receiving the ball (and he seems to favor his right hand). :) Enjoy the giggles towards the end, too!
