Bonnie on the Move

Bonnie has been flirting with the idea of crawling for a week or so. She gets in the crawling position and she rocks back and forth. However I think she's just teasing me and as as soon as I turn around she's crawling all over the place. I put her on her play mat and went upstairs to set something in my room, I was gone for probably 30 seconds, and when I came back I was like uhhhhhhh...... there was a baby here when I left?!
