I don't know about you, but to me, the term "Designer Baby" sounds wrong. Designer Babies are:
The colloquial term "designer baby" refers to a baby whose genetic makeup has been artificially selected by genetic engineering combined with in vitro fertilisation to ensure the presence or absence of particular genes or characteristics. The term is derived by comparison with "designer clothing". It implies the ultimate commodification of children and is therefore usually used pejoratively to signal opposition to such use of reprogenetics
"Designer clothing" is understandable, because "designer clothing" is clothing that bears the logo of a recognizable fashion designer. That means, "clothing that has a designer's mark on it, hence the term "designer clothing", the clothing of a designer."
But "designer baby" doesn't make sense to me. "Designer baby" isn't the baby of a designer. It's just a baby that's been designed artificially.
Do you get me? So, shouldn't it be "Designed Baby"?
