New tricks

Will learned 2 new tricks today! We went to the park and he started crawling like this...

I guess he doesn't like crawling on the grass!

And then all of a sudden, he stood up all by himself!!

It was the first, and only time he's done it, so I'm glad I had my camera ready!

And then later he was playing with a cup and realized his voice echoed in the glass. I think it is so neat to watch him discover little things like this!
