Three babies is just a way to condition the public into accepting an updated version of eugenics, this time called bioethics.
The Human genome project already mapped out our whole DNA and the public would be astonished at what is already possible (and probably has been done behind closed doors).
We are moving towards the vision of Aldous Huxley's Brave New World:
In the very near future, in the name of efficiency, the only people who will be allowed to be born are those that have jobs that they were specifically born to do, and they will be tailor-made for the jobs that they were "created" to do; and they will be implanted with microchips to govern their thoughts(none of their own) and actions too.
Abortions, Euthanasia, and advanced screening of couples ahead of time wishing to have children are all just steps along the way to a totally planned society where the individual will no longer have any free will but instead be a perfect automaton of the state.
