My little inchworm

Baby B is still a ways from real crawling, of course, but she's definitely making moves in that direction. She's been able to spin herself around on the floor pretty easily for a while, but now she's able to lurch forward about two or three inches at a time, especially when she pushes off something with her feet. It's so hard to fathom the fact that she was just a helpless creature who only slept, ate, and pooped not all that long ago. How is this the same person?!
