I work a lot with pregnant women and they all want to know about the very best music to listen to during their pregnancy. Of course I always tell them that their voice singing to their unborn child is the best. The mother's voice is the one that baby hears first and most often while in utero and therefore that one that makes baby feel safe.
But what about Mozart? Well, many Marketers jumped in on the whole "Mozart Effect" media blitz and said that Mozart would make your baby smarter, happier, sleep better and all kinds of wonderful things. To my knowledge, no research has ever proven or even suggested that, so decide for yourself. Mozart certainly is not going to be bad for your baby but mother's voice softly crooning to baby is undoubtedly the best!
