River, age 21 months, loves to draw. Most of River's drawings to date have been lines. She's practicing making a mark on paper, exploring color and just beginning to control the marker or colored pencil. She usually names her drawings "moon", even when all I can see is straight lines. Only in the past few days has she started to make something resembling a circle. When she drew the orange lines ("Flower", bottom left), I told her I thought it looked like a flower, and colored in some of the petals. She then picked up the green marker and added the leaf. I think it's our best collaboration yet.
