Paradise undeserved

Duet time; Emma loves the piano and points up to it when she wants to play, rubbing her belly for "please." If I don't sit down with her, she points to the keys and looks at me, saying "dis." I ask her, "Where is middle C?" and she picks any note and plays it over and over again. She also just started to sing while I am playing. She can't sing while she is playing, but I think that will come with time.
