It has been disproven that Classical music does anything more or less for a baby's development than any other kind of music. This series builds off people's hopes/desires to build a better baby by simply playing a CD. If only life were that easy! What makes matters worse is that the quality of the music on these "XXXXX for Babies" series CD is uniformly bad.If you want to play Classical music for your baby, wonderful! But by all means go to the Classical Music section of Amazon and by the best possible recordings of the great composers and forget about these slick marketing gimmicks aimed a gullible (albiet lovingly so)parents-to-be.
