I was unloading groceries from the car and placed Bug on a blanket in the middle of the living room on her back. In the two minutes I was gone, this little stinker had scooted backwards about 4 feet. Off her blanket, off the rug, right onto the wood floor. She is only two months! I don't remember Bear doing this at this point. I have a feeling that she is going to be an early mover. Lord help me.
