This intriguing product delivers 16 varied sounds that resemble a mother's heartbeat to your child while in your womb. Designed to be played for 1 hour twice a day, the sonic pattern introduces baby to a sequential learning process, based upon the natural rhythms of the womb. The rhythm of the sounds increase incrementally as the pregnancy progresses. The claim is that this "auditory exercise" strenghens learning ability during the developmental period when the advantages are believed to be most significant. Baby is thought to learn to discriminate between the sounds coming from the mother and those from BabyPlus and that this process, in turn, will build your baby's memory and learning skills. BabyPlus claims that children will have an intellectual, developmental, creative, and emotional advantage from the time they are born. Other intended benefits are thought to include: better sleep, improved nursing, better interaction, greater responsiveness, improved attention spans, meeting developmental milestones. $149. 18-32 wks.
