She also went from refusing to put anything in a container for me (she would occasionally do it for others) to putting shapes into a shape sorter. She can only do round and square objects but she is doing it on a consistent basis. If I hand her a ball, she knows exactly where it goes. She is also stacking rings on a ring stacker.
Sophie loves music. She loves bouncing to music and her new thing is clicking her tongue to music. The first time she did it was about a week ago at 1:30am. Sophie would not sleep so I got her out of bed to let her play. As I laid there half delirious, she started clicking her tongue to the ABC song playing on one of her toys. If she didn't do it again the next day, I probably would have thought I was hallucinating. Now she clicks her tongue to all kinds of music. It is her way of singing. Also, while Sophie is standing, she will hold on to my hands and I will rock her back and forth while singing Row-Row-Row-Your Boat. Today, she came up to me and held on to my hands and started leaning back.
So those are her newest things, at least, all I can think of at the moment.
