Very stressful approach to "infant learning" IMO. The book stresses the importance of being a "professional parent" and willing to take all the time necessary to teach your child, to prepare "learning" materials, etc... Sound theory in and of itself... but the "Multiply Your Baby's Intelligence" program is all about flash cards.... flash cards for math, reading, and "bits" of encyclopedic information being presented to infants from a very tiny age. Might result in a child w/ lots of facts in their head at a young age, but is that really learning?
