Eric, getting ready to walk

Eric has completely mastered crawling. He is so fast that you can put him down in one room, run out into another room and seconds later you'll see his little head poking out around the corner. He just takes off so fast that he has calluses on his knees and tops of his feet.
He has also mastered the standing holding things skill. He will cruise from one piece of furniture to another and just within the last week or so is attempting to stand without help.
I've seen him standing, holding the couch then let go for a few seconds, but today I saw him stand without help! He had a little help because he used the step to get up, but stood there with a big grin and when we all cheered for him, he did it again.
He is really good at pushing his push toys around and Lily, ever so jealous, is constantly taking them away. We finally found a solution, one rides, one pushes. The following video only has a couple of steps of Eric pushing, but he actually pushes her all over. It is really sweet.
