Standing!
Yesterday, we were hanging around in the back yard with some friends. Ethan was crawling around chasing the soccer ball and volley ball in circles as he sometimes does. Suddenly I turned around and he was standing in the middle of the yard - with nothing that could have helped him up close by! So he has officially stood from a seated position all on his own. He just stood there for a while and looked around before casually dropping to his hands and knees and crawling towards the dogs. Like he's been doing this for years...
