He's a MONKEY!!

Teagan is going on 14 months and is still not walking. He crawls everywhere, stands on his own, even gets up from sitting without holding on to anything. I know eventually he figure out that walking is way better than crawling, but for now he has turned into a monkey. I found him on my desk today with all of the contents on the floor. He managed to pull out the chair, get on it and climb onto the desk, all while I was doing a load of laundry. So, he can now climb, crawl, and stand on his own, but he can't walk...what's up with that?
