Sometimes I run the length of my kitchen and Ellie chases me. I do it like once and she gets the idea and will come tearing after me. Then I run back and she runs as fast as she can to come get me! Its really funny.
But mostly she just plays by herself. I have a ton of different toys for her, wiffle balls, TP/PT tubes, sheets of cardboard, boxes, plastic slinkys, a few stuffed animals, and always a section of the Sunday paper. She tears up the paper and does whatever with the other things.
Right now, she's digging in my floor and she seems to love that! haha.
