As you can see, she doesn't really get up into a crawling position, yet. But she's on her way. She also scoots around the floor (only backwards—she hasn't figured out how to go forward, yet), pivots on her belly, and leans forward from a sitting position to reach toys that are out of her reach (which can eventually lead to a crawling position). Leann feels a slight sense of dread at the possibility of Lillian being motile.
 See my post, Yarn.
