I bought this video for our 15-month old. He is moderately interested in it for about five minutes at a time. I on the other hand find it positively creepy. The repetitive chanting of the children's voices and the claustraphobic computer-generated imagery seem intended to put a child into a trance-like state. Well, at least that's the effect it has on me. There is none of the joy of visual experience so evident in the Baby Mozart series. Miracle of Mozart, "Numbers and Shapes" has nothing extraneous, nothing present simply for the delight of the eye. It's geared exclusively to stuffing numbers and shapes into the baby's head. I find this single-mindedness quite disturbing for a tape geared to infants. Is early success so important that we have to sacrifice fun ? Incidentally, it is extremely hard to imagine any child over 2 sitting through this video, even though the age range is 8 months to 5 years.
