She crawls with no assistance needed! I like to put down TONS of pillows around her. Subconsciously I'm thinking that the pillows will "contain" her in the immediate area that she's in...
I can't really pinpoint the exact moment she started to crawl. She practiced a lot while I was at work. One day I came back home and saw that she could crawl from one side of the living room to the other side, on her stomach using just her hands (think military style).
One day, she just popped up her on her knees and started to crawl.
She's definitely no "expert" just yet but, like everything, it's only a matter of time.
We need to start child-proofing the house. Maybe that will be a good activity for this weekend.
