Here are some examples of her latest feats (in addition to escaping through the dog door):
She climbed in this toy bin herself. She couldn't quite figure out how to exit it though. She would get frustrated, then play with some toys for a while, then try again.
She loves climbing on the step of this toy (which also happens to be the loudest toy on the planet)
Quite competent with her walk behind toy although she can't back-up yet.
I wish that I could say that standing is a new thing, but she has been doing it for a few weeks now. She can even squat down then stand back up then squat again then stand up...well you get the picture. I tried imitating her but discovered that it's really hard work (great for the leg muscles though)
