Choosing how a child turns out at five as a basis of which kid you want is clearly something that produces a non-trivial eugenic effect. Not in the societal sense (since what kind of kids a society gets are mostly already set), but in the sense of shaping the child you get to have according to one’s own preferences. It is perfectly comparable to choosing the foetus with the right genes for implantation.
