We read to Roxi three times a day - before both her naps and before bedtime. She surprised us recently by turning the pages for us. You have to "prep" the next page by flipping it open a bit; Roxi does the rest by herself. Sometimes she gets so excited about seeing the next page that she reaches for it before you can finish reading the current one.
Page turning! Can full-fledged literacy be far behind? OK, probably. Still though, all signs point to an appreciation for books ... and not just chewing on them.
