Ellis has this super silly crawl

Ellis has this super silly crawl. It is so hard to describe so I will try and get it on video before he stops doing it. I think it comes from him pushing cars around all the time. He uses one hand and one leg to crawl. The other leg he sort of scoots behind him. It makes for dirty pants! Ellis signed help for the first time tonight! I have showed him a few times how to do it, but not very consistently or very often. And he did it tonight when I asked him if he needed help (without signing) when he could not reach a toy. He excitedly signed help and did it all night (mostly because I got so excited I am sure) for everything.
