These books are one of the greatest gifts you'll give your kids. My grandparents and my parents fostered a love of books in me at a really young age by making sure we spent a lot of time in libraries, bookstores (remember those?), and giving books as gifts during Christmas and birthdays.
I write this response from a library as I prep to work on another piece of writing about a curiosity first fostered long ago by my loved ones.
