I second what eternaltraveler says, you shouldn't be using perfectly healthy children as your "baseline" in your nootropic experiment. Use yourself, and if you're really interested, ask your friends to try some stuff out. It's one thing to experiment with hardly-studied, powerful psychotropic drugs on yourself, it's a whole different story when you're experimenting on your own children's developing mind.
That's like saying, "I want to see if mushrooms will bring me to baseline, so I'll feed my children a few and see if it brings them above/below theirs." Come on, use your common sense as a father/mother....
I totally agree, and did I write what they were taking? "No".
An assumption is made that both children are "perfectly healthy" without actually knowing that. One child is mentally challenged, and Piracetam for example, has been indicated to increases performance on a variety of cognitive tasks among this group.
"Experimenting" on people is what physicians do everyday, and on nearly every patient they see. Physicians change medications and dosages regularly to "see what works". They inject substances into our bodies and subject us to "tests" hoping to diagnose a malady.
Are Zyprexa, Abilify, Concerta, Effexor, Lamictal, Klonopin, Adderall or Depakote good for my child because a physician prescribed them at one time or another? Some would say "No".
I think it make sense, even though it may not be common, to help my child have a better quality of life.
I do not want to turn this post into a negative string. Thank you for the thoughts and I apologize for offense.
