Hannah started taking steps before she turned 1, but I'm just now getting around to taking video of her doing it. She's become a very fast crawler, and even crawls very well up on her feet out of necessity (this is shown in one of the videos and is pretty comical). But she loves to stand up in the middle of crawling and take a few steps, which are becoming less and less wobbly. The funny thing is that she takes more steps when she has a toy or something in her hand rather than when her hands are free.
In the video below, Hannah is walking while pushing a little toy stroller. Unlike the activity walker, you cannot lean on the stroller without it toppling over. So she is basically just using the stroller for added balance (however slight) while walking.
