Sadly, there are not so many ebooks available for young readers yet. You might have to scan some of your collection. (I keep meaning to scan my Rumer Godden books.)
Still, plenty of kids are learning to read while playing with these games, too, and you can pick games that involve more reading (roleplaying games, for example). Or see what she thinks of Brain Age.
Or install one of the DS ebook readers and slip a few choice books in there.
