K.G.
While I don't know enough about the program, we read to our boys from 6 mo of age until they were reading on their own...and even then they would ask us to read to them now and again.
My kids were both reading some words at 3 & 4 yrs old and able to sound out bigger words. They both read off the charts for their grade levels AND comprehended what they read.
By what I have heard about the program, I'm not sure the expense outweighs the parent & child bonding of sitting cuddled on the bed and reading together.
Just my humble opinion.....I wouldn't trade those times for books with audio/video tapes that cost alot of money.
