I bought my dd the videos, "Meet the Sightwords," which are sight words in pictures when she was about 2 1/2. The only reason I got them is because her older brother has dyslexia and in the off-chance she did, too, I wanted to expose her to words early. But she loved watching and she also loved the flashcards that go with the videos. I knew right away that she didn't have dyslexia because started reading other words right away and was a fluent reader by 4. It might have been this early exposure that helped her crack the code, or she might have been an early reader anyway like her DYS brother.
