Query: Love this DVD

My son, who just turned two, has been watching this DVD for about a month. He knows 75% of the letters. He can identify the letters and say the letter and/or make the sound. We also have the Leapfrog Fridge Phonics Letter Set which has played a large part in his learning. My son only said about 20 words up until a month or so ago, so we are astonished at how quickly he has learned the letters and he now says over 50 words. This is one of the best DVDs we have. I also got the Word Factory and I know we will love that when the time comes.
