Sesame Street

What is it about Sesame Street that is so intriguing to little kids? I remember when I was young just loving it, and now I have a daughter who loves it just as much if not more! It's neat that they still run the show...as there are so many classics that they don't anymore. I think it's a mix between the characters and the music. What I love is how much learning goes on at the same time. She has started counting and saying her letters which is just great!
