This is a classic video taken a while back showing the funny interactions between the boys. Eli telling Charlie what to do, Charlie mostly ignoring it and doing what he wants and having fun.

And this is a clip of Eli reading a book to himself early in the morning a few weeks ago (I heard him reading when I came down the stairs and grabbed my camera to quietly capture it). He had gotten up before me, eaten breakfast, played with blocks (and made a big mess), then snuggled under a blanket on the couch and started reading this book out loud to himself.
