Helen might start walking soon.
Last night she was standing up, propping herself up with one hand on my chest. Then she took her weight off me and just held on to my T-shirt. She wasn't really pulling on the T-shirt; it was probably more for reassurance than anything else.
At the same time as working on balance, Helen is also working on the required motor skills. This morning she walked about 25 feet while holding on to my hands. And she walked pretty fast, too!
