Pink Walls

Pink is Lillian's favorite color. The other day she asked me why her bedroom walls are green. I told her that we did not know if she was going to be a boy or girl and thought that a light green would be a good color for the walls. She then said to me, "I don't like the green walls. I want pink paint." I don't know where she learned that you can change the wall color - we have not done any painting since she was born and have not talked about painting anything.
