My 20-month old is VERY interested in reading and seems to want to learn how to do it. He constantly asks me to spell out words and when we read books he always tries to "read" along.

How can I encourage this behavior and take it to the next level? I wasn't expecting him to show signs of being ready to learn how to read so early and I haven't gotten to read up on the subject. Any good books/tools I can use? He has various phonics toys, TONS of books and a Little Leap Pad. Any other things that help with early reading?
