I really don't understand how people can intelligently think that the baby that is brought into this world at birth is substantively different at *any* point from conception onwards.  The artificial distinction between embryonic cells and a baby is so incredibly arbitrary that it simply defies reason.  And the evidence keeps mounting towards this inescapable conclusion.

Now scientists indicate that being rocked like a baby improves the ability rates of in vitro babies, perhaps by as much as 20 percent. 

Note the carefulness of the people interviewed to refer to the young babies produced simply as "cells".
