Read to your children when they are young. Most toddlers love being read to. So long as the book is short enough to hold their limited attention span, most 18-24 month olds will happily sit in your lap and let you read. They also like to turn pages. Even younger kids like being read to, though their attention spans often do not last long enough to read a full book when they are very young.
From there if you don't discourage reading, but don't make it a chore that must be completed, many children will simply want to read.
