Designer Babies

I think designer babies is ridiculous. I belive that the baby shouldnt be messed with. Even if you could make sure the baby doesnt come out with a disability or a feature you wish you could have changed. Also what happens if the baby you designed didnt come out the way you wanted? it would have been a waste of  money. It should be all natural like how it was in the past when technology as such hadn't existed. Finding out the sex of the baby is fine because your not messing with the baby to make it "perfect".
