Mothers report this to be comforting, and have confirmed that their babies anticipate, recognize, and seem to enjoy this activity. Virtually every mother who has ever used the BabyPlus system emphasizes that it has been a tremendous bonding opportunity and experience.

Since 1989, parents in more than 60 countries worldwide have given their children the BabyPlus advantage.

The BabyPlus Prenatal Education System is at the forefront of the 21st century learning revolution.

Similar Product Comparison


If not exhaustive, this list constitutes the commercial majority of relevant items; each is assigned a numerical value based upon fidelity to the unborn child's documented environment and capabilities--namely, whether a product can demonstrate consistent effectiveness as measured by independent and controlled clinical trials, or how well an author has comprehended the theory, dynamics, and meaning of their focus. 


Comparative studies substantiate that all merchandise rated "insignificant" evokes no professionally measurable result other than a minor placebo effect perhaps signaled chemically to the womb--which mothers can initiate no less through any pleasurable experience.

RATING: 5 Stars

The BabyPlus Company, Fishers, Indiana. Specially designed battery powered microchip technology generating 16 rhythmic sound progressions based upon the maternal blood pulses every developing baby experiences 24 hours a day. If the unit is clipped to clothing on the abdomen, these curricularized variants are played to the developing baby for an hour twice daily through the unit's own speaker, or with optional twin speakers which are contained in a fabric belt surrounding the mother's abdomen. No other product or technique has demonstrated through controlled, independent comparative testing the consistent cognitive, social, and creative advantages of BabyPlus. Available through major outlets, maternity shops, mail order and Internet e-commerce locations (see this website for sources). 

Bebe Sounds Prenatal Teacher
RATING: 1 Star

Unisar, New York. An abdominal belt with speakers, one musical audiocassette (supply your own player). Its wholly unsubstantiated claims include increasing IQ, fetal brain development, motor improvement, better child learning and interaction. Repeated requests for the clinical data behind this product have gone unanswered; professional endorsements of its value are either entirely questionable or taken out of context. Price $24.99. 

Womb Song
RATING: 1 Star

Munchkin Corporation, Van Nuys, California. This product is merely an audiocassette player modified with a microphone and abdominal belt. Its wholly unsupported claims include: 

1. Parent-fetus communication--since research microphones placed inside the womb amply detect adjacent speaking at normal sound levels, why amplify? Apart from some volume reduction and muffling, the unborn child experiences virtually all sonic activity in the mother's environment, so the key factor remains which material is appropriate. 

2. Parent-fetus bonding--favorable chemical and/or hormonal changes which cross the placental barrier occur whenever a mother engages in any practice she enjoys; why not eat ice cream? 

3. Fetal learning from music or foreign languages--a nearby CD or tape player at normal volume provides the same; although headphones were stretched across pregnant abdomens since 1980 (when the Sony Walkman was introduced), there is no clinically controlled evidence that stimulation from content-oriented material benefits children. 

4. Proof--The product's inventor and spouse "proved the concept to their own satisfaction," which is hardly reassuring; except for Brent Logan's BabyPlus technology, none of the other products evaluated here has moved beyond anecdotes--they have not met the minimal scientific requirement of clinically controlled comparative testing, with results published in the professional literature. 

RATING: 1 Star

Arvada, Colorado.; Much like the Prenatal Teacher with the same deficiencies. Again, because music or spoken material amply access all unborn children anyway--without demonstrable effect--products which simply duplicate what is in the standard fetal environment are unnecessary. The fabric belt and speaker is priced at $49.95, including an audiocassette player for $69.95; future options will add heat, vibration, and a heartbeat monitor, all of which are available to parent without cost--wear warmer clothing, exercise or on your next practitioner visit, ask to listen. 

Tummy Tunes
RATING: 1 Star

Alabama. A virtual copy of the Prenatal Teacher or Edubaby, this version can be purchased as an abdominal belt with speaker for $19.95, or includes a tape player at $29.95. No cassettes are included, which leaves the sonic content up to parents--so why not speak louder or just turn on the television or CD player for the same result ... none beside an insignificant placebo effect. 

RATING: 1 Star

San Luis Obispo, California. A nonelectronic voice amplifier, thus a rather expensive megaphone; slightly raising one's voice achieves the identical purpose. 

Fetal Phone
RATING: 1 Star

Bixby, Oklahoma. Like the Pregaphone, another wholly unnecessary device; the inventor maintains it delivers 100% of a mother's voice to her fetus, when even elementary school science points out that no matter how much sound goes elsewhere only the received decibel level matters. Every unborn child will hear a parent just as well if they raise their voice--no additional amplification is needed. 

Rock-a-Bye Music System
RATING: 1 Star

Munster, Indiana. Designed for prenatal application, a fabric apron with pockets which fit audiocassette or CD players; however, since fetal stimulation by noncurricularized music is verifiably ineffective, and this apparel lacks appropriate speakers (headsets are extremely awkward and uncomfortable when stretched across the abdomen), the invention joins those without adequate forethought. 

Mozart for Mothers-to-be
RATING: 1 Star

Polygram Records, New York, New York, As with all noncurricularized sonic material presumed important for the fetus, were music by Mozart--or Madonna--in any substantial way helpful, the result would appear in comparative postnatal evaluations; such a benefit has never been clinically demonstrated. Not only do infants exhibit considerable preference for childhood melodies and simple lullabies over the far more sophisticated structure of classical music (an appreciation college courses teach), since most sounds in the maternal environment reach the fetus anyway, why should a headset across the mother's abdomen improve upon Mozart more than the same composition broadcast on radio or television? If so, every unborn child must be equally advantaged because, as verified by hydrophone, similar sounds are always penetrating the womb. 


While a few general trade works serve as precursors to the new discipline of in utero stimulation, their treatment is often tangential though some do report Brent Logan's research: 

Super Baby: Boost Your Baby's Potential From Conception to Year One, by Dr. Sarah Brewer M.D., Thorsons, London, HarperCollins, New York, 1998. With the BabyPlus technology as its centerpiece, this parents' guide by a British physician--who stimulated her own child with the product, and is author of several popular healthcare books--explains prenatal enrichment in lay terms; despite some errors (such as not understanding that music and verbal stimulation have demonstrated no lasting fetal value), Super Baby prefaces a more extensive treatment in Brent Logan's Learning Before Birth.

RATING: 4½ Stars

Learning Before Birth: Every Child Deserves Giftedness, Brent Logan, Authorhouse Publishing, Bloomington, 2003. The first repository of complete information about an ancient parenting practice now technologized as a developmental enhancement, scientific discipline, commercial industry, evolutionary dynamic, and quantum cultural advance. From theory to application, the entire field is examined in detail, discussing its history, central ideas, clinical trials, global results, and implications--for individuals as well as society.

RATING: 5 Stars

Prenatal Classroom: A Parent's Guide for Teaching Your Baby in the Womb, Rene Van de Carr and Marc Lehrer, Humanics, Atlanta, 1992 (revised paperback 1997, retitled While You Are Expecting: Your Own Prenatal Classroom). In 1979, California obstetrician Rene Van de Carr developed a technique for fetal stimulation employing abdominal manipulations paired with verbal commands; after a decade offering classes for parents, he and psychologist Marc Lehrer transcribed these instructions as a book promotive of family bonding. 

RATING: 4 Stars

How To Have a Smarter Baby, Susan Ludington-Hoe and Susan K. Golant, Rawson, New York, 1985 (paperback 1987, Bantam, New York). This usually helpful work begins to correlate brain research with early learning, specifically infant development, while briefly recommending sonic stimulation before birth. Formerly, a Professor of Maternity/Child Health with the University of California at Los Angeles, Susan Ludington-Hoe also invented a wide range of black-and-white postnatal products, and is considered the driving force behind infant stimulation. The volume remains one of very few worthwhile aids for parents confronted with a welter of postbirth products and practices claiming educational value.

RATING: 3½ Stars

Magic Trees of the Mind: How to Nurture Your Child's Intelligence, Creativity, and Healthy Emotions from Birth Through Adolescence, Marian Diamond and Janet Hopson, Dutton, New York, 1998. A repackaging for parents of Marian Diamond's 1988 Enriching Heredity, with extensive resource listings. Although recommending prenatal stimulation, she--and the cited advice of other researchers--surprisingly overlooks the high sonic volume from omnipresent intrauterine noise which is obviously not injurious to the fetus, therefore suggesting approaches too brief to imprint. 

RATING: 3½ Stars

Enriching Heredity: The Impact of the Environment on the Anatomy of the Brain, Marian Cleeves Diamond, Free Press, New York, 1988. For thirty years, University of California at Berkeley Professor of Neuroanatomy Marian Diamond has stimulated or deprived rodents, tracking their behavior and examining how such influence alters the brain's physical structure. Among her experiments she shows that rat pups exposed to various interventions prenatally perform much better at maze testing.

RATING: 3½ Stars

Caring for Your Unborn Child, Roy Ridgway, Thorsons, Wellingborough, Northamptonshire, UK, 1990 (paperback 1991, Harper & Row, San Francisco). A readable blend of popular psychology and pregnancy tips is contained in this generally practical handbook which devotes one chapter to prenatal learning, discussing Brent Logan's contribution at some length.

RATING: 3½ Stars

The Expectant Father, Armin A. Brott and Jennifer Ash, Abbeville, New York, 1995. Containing well-intended though rather obvious points about a frequently ignored aspect of parenthood, this pragmatic treatment notes Brent Logan's technology.

RATING: 3½ Stars

The Secret Life of the Unborn Child, Thomas Verny and John Kelly, Summit, New York, 1981 (paperback 1982, Dell, New York). Mostly anecdotal, absent much theoretical basis or empirical evidence, at least this volume draws attention to the prenatal period's importance upon later health and behavior. Despite support for the outcomes from fetal enrichment--and later editorial inclusion of Brent Logan's published studies--Toronto psychiatrist Thomas Verny maintains an anti-technology perspective which makes difficult any thorough understanding of such rationale or function.

RATING: 3 Stars

Babies Remember Birth, David B. Chamberlain, Tarcher, Los Angeles, 1988. Like Thomas Verny's book, this remains a collection of prenatal and perinatal anecdotes though adding some quantitative findings; with a concentration upon maternal-child bonding, his approach draws more upon subjective judgement than it admits, an ongoing problem for the "soft" sciences.

RATING: 3 Stars

Brighter Baby, Brenda Adderly and Jay Gordon, Lifeline Press, Washington D.C., 1999. A superficial treatment of prenatal and infant stimulation products, failing to identify music and spoken material as ineffective. The BabyPlus fetal enrichment system is noted.

RATING: 2½ Stars

Requiem para Batman: Biografia Provisional de un Nifo Prodigio, Manuel Alonso, Federico Domenech, Valencia, 1990. An often self-serving Spanish account of a child prodigy--"the new Mozart," performing in public concerts and privately before Europe's royalty--by his father, which describes instrumental stimulation practiced by the mother prebirth; one chapter reports Brent Logan's provision of a conceptual basis for the phenomenon, along with recalling his assistance in acquiring an American scholarship for this virtuoso. The boy's parents market several musical audiocassettes which they believe promote fetal advantage, but this assertion has not been verified by independent comparative trials.

RATING: 2 Stars

Nurturing the Unborn Child, Thomas Verny and Pamela Weintraub, Delacorte, New York, 1991 (paperback 1992, Delta, New York). A month-by-month gestational guide that presumes mental communication with the fetus; this dubious direction reinforces the speculative precedents expressed in Thomas Verny's The Secret Life of the Unborn Child. As Senior Editor at Omni magazine, Pamela Weintaub first gave national exposure to Brent Logan's research in an August 1989 cover article entitled "Preschool?".

RATING: 2 Stars

The American Way of Birth, Jessica Mitford, Dutton, New York, 1992. As spirited as her 1963 The American Way of Death, this is a mainly accurate indictment of the United States medical establishment; although erroneously referencing Brent Logan's innovation, these inaccuracies were corrected in a 1993 BBC Television production of the same name, which includes an interview with him.
