child size

I read this article today and still haven't decided what to think. I would like to think that the parents have their child's best interest in mind, but I don't know. I would not want my parents running my life. Then again I have the mental capacity to know that, does she? It is really odd, I'm all for the advancement of medicine and use of science (though I think it will be the demise of the human race), but at what capacity can you use it to control someone else's life? What are your thoughts?
