I have always loved reading...and so I especially love seeing children "reading" at any age!!
I like this quote:
"I would be most content if my children grew up to be the kind of people who think decorating consists mostly of building enough bookshelves."
~Anna Quindlen, "Enough Bookshelves," New York Times, 7 August 1991
I find that a great source of quotes can be found at the following location (you can even search by keywords -- such as "books" as it shows in the link below). Hope this helps.
