CEF has started scooting around on the floor. She uses both elbows and one knee to get around. She is not very fast — until you turn your head and then she has gotten into something before you can look back again.
The other day she was on the living room floor, on her stomach, and I called her to come to me. I didn’t really expect her too, but she started scooting to me and made it to my shoes, where she then go distracted by the laces. Then this morning she was at the beginning of the hallway and had started fretting when I disappeared into the bathroom. So I tried calling her to come to me again. She made it about a third of the way down the hall and then she rolled on her back and started cooing at the ceiling.
