At nearly 14 months old David is still not walking. He certainly seems to want to as he sometimes tries to stand up but can't quite figure it out. And once he does stand up he gets very nervous and then slowly squats until he is sitting again.
These videos show some of his progress in this area. This first one shows that he at least figured out that he is supposed to be on his feet instead of his knees.
Probably, however, he just does this when his parents are too mean to put pants on him while he crawls around on the cold hard floor. Hence the crying.
The next video shows David progressing even further. We never knew that his highchair could double as a walker.
But as you saw, in the end, he abandoned the entire endeavor to just continue crawling. Maybe someday he will figure it out.
