I often hear Sophia 'reading' her books in various places. It is all jibberish to me, but she will sit there for fifteen minutes at a time and just tell story after story as she 'reads' her books. This day I kept her in her highchair after snack while I did the dishes and David caught a glimpse on tape.
This video is much longer than normal, but just to give you an inkling of her animation and captivation with her books. Who really knows what is going on her little brain, but it sure is fun to watch.
