My daughter is four and has had this book since she was about 10 months to a year-old. I have played it for her when she goes down for a nap and at bedtime over the years and now play them for she and my son in the van on our travels around town.
Even though she was too young to fully comprehend all that is on there, she REMEMBERS what she has heard and has repeated things back to me and asked questions.
I am now teaching her memory verses and she knows eight so far, one of them being John 3:16, which is pretty long for a little girl. My son is learning them as well, and knows one so far (he's two).
I highly recommend this book and the tapes/cd's that go along with it. In fact, we originally recevied this as a gift with the cassettes. We wore the cassettes out and I was fortunate to be able to get just the cd's online without having to buy a second book.
Adults could become a little annoyed at the voices used for the animation, but as the Lutheran mother above wrote, her daughter loves it. Kids are attentive to dramatic voices and would likely just ignore someone reading in a manner that would please the Lutheran mother's ears :o
It's a wonderful book for Christian parents who want to teach their children about the Bible. Everything in there is scripture, so no matter what denomination, if you believe the Bible is the infallable Word of God, this book is for you.
