Standing Up

It seems like every time I turn around one or both of the kids have pulled up on something.  They can get from crawling to sitting, sitting to crawling, and as you can see, they can stand up all by themselves!  Now that they've figured it out, they love to explore all day long.  They motivate each other too.  If one sees the other standing, the other isn't far behind.  And they're fearless.  The other day I started singing the Itsy Bitsy Spider while they stood next to something they had pulled up on, and they clapped -- which means they weren't even holding on!
