Last night Tatiana did the cutest thing!  The three of us were in the living room.  The toy box was in the middle. It was mostly empty because I'd dug through to get her buckets to make a tower.  She dug in her toy box looking for something and then her feet left the ground.  At one point she was balanced on her waist on the edge.  Scotland and I simultaneously said, "Look at that!"  I ran for the video camera but when she tipped over into the toy box, she was a little upset and Scotland rescued her.  She was digging for an empty thread spindle.
