We bought this Bible for our son when he was 18 months old and he immediately loved it. The version we bought came with the cassette tapes, and he really enjoyed listening to the stories and songs in the car. Unfortunately, he practically destroyed the pages of the Bible at that age, and it's now all taped together.
We later bought a new Bible & CD set (since our newer vehicle doesn't have a cassette player) but have kept the old one as well. Our younger son now enjoys looking at the old Bible and the older son looks at the newer Bible (since he can now take better care of it). He also takes it to church with him.
I am not too crazy about some of the songs on the CDs...some of them are fine, but others are "fluff" and rather silly-sounding. I realize that this may appeal to children, but I would prefer to have more sound, reverent music accompanying the Bible stories. We are teaching our kids hymns, too, so no harm done, I suppose. So that's the reason for 4 stars rather than 5 stars.
At any rate, I still highly recommend this Bible & CD set. From listening to the 4th CD almost daily, I discovered that my son (4yo) was able to recite, with little prompting, the first 8 pages of the New Testament! Very exciting for us!
