Some things to look for:
1. Asher is a speedy crawler these days.
2. He can stand up and balance on his own for just a few seconds.
3. The second time he falls down he actually busts his lip, but he never notices. Roger noticed at the very end of the video.
4. After he falls down the second time he gives my leg a kiss. Listen carefully and you can hear the sweet little noise he makes when he gives kisses.
