It is obviously not his first choice of transportation, he is still shaky. I knew he was getting close because he has been cruising around forever, stands without holding onto anything for long periods of time, bends his knees to pick up items up off of the floor from a stand, and on Saturday he stood up without pulling up on anything (I missed this... Carl got to see it). I was so proud of him! It was just amazing.
If I were you I would turn the volume down because all of my cheering is kind of annoying. And these weren't his first steps.. but his second set.
