First the rich will do it, some in secret eventually unapologeticlly, to insure their designer kids have a step up. These designer kids will be the ideal fawned over by society in the media, and on this forum.
Any un-enhanced kids, now pressured and taunted by society for being "normal", will blame their parents for their inherited genetic physical, and mental "weaknesses & shortcomings"
Any who consiously abstain on now outdated moral grounds, will be marginalized by society as backwards, weak, ugly , dumb and creatures of the past.
When it's finally affordable, everyone will start doing it. just so their kids can "fit in" and compete in a world that caters to those enhancement ideals now shared by most.
Eventually everything; looks, intelligence, height, race, etc culminating in one homogenized look and eventuaklly gender, as none will want to have their kid being discriminated against or be biased on one over the other, so they'll all be born with both genders, i.e there won't be gender, it will be a non issue.
A generation will be born where all humans will be so genetically similar pulling from the same idealizes stock, reproduction through breeding will disintegrate, as there will be no variety of genetic information being exchanged. The equivalent of over-interbreeding.
And collapse of human race.
With the ability to reproduce destroyed, cloning becomes the norm, and we fianly have a society of a same self replicating hermaphrodites.
Congratulations, the perfect human cockroach....
fyi amalgamation of Will Smith, Brad Pitt, Tom Cruise, Penélope Cruz, and Angelina Jolie.
but I would make my kids better than me, but give them wizard powers. No, X-Men powers. Singing ability, no speech problem, higher I.Q., and super powers. 
and, eh, they be mutants.
cause we would be THE GODS! MUAHAHAHAHAHAHA....-_-.
