This morning, as NJ was playing and I was guzzling coffee here at the desk, she looked up from her pile of toys and gave me a half cry. I started talking to her and she did it again, a little louder and a little whinier. Then she raised her arms. I picked her up and she let loose a yawn that lasted about twenty minutes. I took her upstairs and she was asleep in her crib before I could get out of the room.
It beats the last time she outwardly indicated she was ready for her nap, when she just fell over asleep.
