Our bookworms read a wide variety of books. From short stories to 700-pages novels, comics (or graphic novels if you prefer) to joke books, we have them all.
Even for the Dolly, who can now read wordy pages, she still finds a great deal of enjoyment from reading picture books meant for 2-4 years old.
My 10-year-old Chippy can also be spotted flipping through longer picture books meant for 4-8 years old when he potters around the house.
We tend to buy more than borrow, simply because time is scarce so we rarely made it to the libraries. Since we have three kids, and they like to read the books repeatedly, we figured it is worthwhile investing in the good books anyway.
The one thing that I like to do more is to get the older kids to read newspapers and magazines. I used to subscribe to the Straits Times and magazines on Science and Technology for a while. Perhaps it is time to resume.
