If you're raising a book-lover who's always looking for a new favorite, Sproutkin's Sproutkit ($25 per month) is a must. Each Sproutkit contains 10 classic and lesser-known books chosen by educational advisers to revolve around a central theme. The kits, for kids ages 3 to 6, also include a Sproutcard with starting points to help guide discussions and activities to ensure your child gets the most out of each book. You can keep the books you want for 10 percent off retail price or, using a prepaid postage label, return them, after which you'll get your next Sproutkit. Depending on how fast you read and return the books, you can get multiple shipments each month.
