It was probably over a year ago Adriana started memorizing books and then "reading" them to me. I was charmed when she could recite all of Madeline. Now she does some of the memorization, but what she really loves are books she (thinks she) can actually read--counting books, mostly, although Sandra Boynton's Blue Hat, Green Hat, with clearly labeled pictures does the trick too.
The other night I got both girls into their pajamas and Adriana offered to read Lyra a bedtime story. Lyra loves the attention from her big sister, and Adriana relishes being in the role of teacher (and having Lyra cooperate with her, which doesn't usually happen). My favorite part, though, is when Lyra is putting her hands on the pages and Adriana admonishes her that if she covers up words, she won't be able to hear the story. It's kind of funny to hear myself as I sound to them.
