Query: BEST EVER Learning DVD's by far

The preschool prep DVD's are the best learning DVD's ever! We own them all and my daughter learned all capital & lowercase letters by 1 year old, and all of the sight words before 2 years old, and is learning to read at 3. I am at home with her and we work a little each day but these video's engage her and hold her attention for a long period. I would recommend all the preschool prep DVD's, starting with letters when they are very young is my recommendation and limit all other TV to less than 1 hr a day!
