1. Start with the obvious: Read aloud, as often as possible, starting when they're young. And don't think you need to be serious or methodical about it. Do the voices, act things out, ask them questions about what they think will happen. For the littlest kids, look for books full of rhythm and repetition. Preschoolers and young gradeschoolers will love goofy humor.
2. Comics can get kids hooked on books even before they can read. The visual layout helps kids get the gist of how to follow a story, and they'll have fun poring over the books even before they understand the words. The old Tintin and Asterix & Obelisk adventures are a great place to start.
3. Keep your eyes peeled for books that can help transition kids from picture books to more advanced reading. The book Dinotopia is a great example. Its lush, detailed illustrations will get kids hooked, but the story is just as compelling, and will engage kids all on its own.
4. Be a good example. Show kids that reading is a pleasurable pursuit, one you truly enjoy and make time for. Keep your own books around the house and talk to your kids about what you're reading, and your thoughts about it.
5. Arrange a reading nook in your house--even if it's just a little corner where a child can curl up with a few pillows and a snack. Make sure that beds, comfy chairs and sofas have adequate lighting nearby.
6. Make a weekly library trip part of your regular routine. As your kids get to know the juvenile and young adult sections of the library, they will get more and more comfortable seeking out the types of books they enjoy. Attend story time sessions with your preschooler, and once kids are in elementary school, consider making a library stop on the way home every Friday, so reading can be a regular part of your weekend fun.
6. Get to know your local librarians and take advantage of their knowledge. Remember, they're reading all the new books that come out in their departments, and can help your child find books in the same vein as the ones they have already enjoyed.
