First Steps?

Jacob pivoted yesterday.  He took one step (with his left foot).  He took another step (With his left foot).  He took ANOTHER step (with his left foot).  And then sat down.

Not linear, but surely first steps...

Here's a video of him pushing his sister's stroller.  So, yeah, he's pretty close to walking.  It doesn't provide much walking help, as you'll see at the end...
