My first child wanted to watch the Leapfrog Letter Factory over and over again. It was her favorite show! She knew all of her letters and their sounds by the age of two. She is already starting to read and she's not quite four yet. This show is amazing at keeping the attention of a child. It teaches the sound of each letter of the alphabet in a fun and memorable way. Each letter has it's own room where the teacher is teaching the letters to make their own sound. Very cute. You don't even realize you are learning when watching it. It's very entertaining and captivating. My almost four year old still loves to watch this show as well as other Leapfrog shows. My youngest child doesn't sit for long when the tv is on, but she will sit still for the Letter Factory and that is saying something! They learn by observing and listening and then months later, they start putting it together and saying their letters and sounds. Awesome show!
