Query: Baby Superstar is based on bad, oudated research.

As a child psychologist, I felt that I had to write in about the Baby Superstar dvds. These dvds are shockingly irresponsible. The "science" that they are based on is outdated, and isn't at all in line with what we in the child psychology and educational communities have been researching over the past five years. These videos are clearly not based on current, peer-reviewed research. The parenting tips on the dvds are also surprisingly out of date, and the "experts" that appear or are referenced are not considered knowledgeable or relevant by the scientific, research, or educational communities. I would not play these dvds for my own children, and I will advise the parents in my practice that these dvds are not suitable or productive for their children.
