By the ledge
In the middle of the room
And in the corner (they LOVE this corner, I don't understand, but they love it!)
And here are a few other pictures from the same day, these crack me up because Charlie is all over Adella, and she didn't mind at all. Most of the time she is fine with it until Charlie kicks her in the face and then its all over. It's so fun watching these two start to play together!
