i'm mainly asking those who know the games. the things that raise the question in 2 follows:
2/3 to 1/2 of the aspirations (your sim's life goal) are kind of questionable. all six are (judge for yourself):
some don't seem too bad, but sims on many of those will have the desire to not be caught cheating in marriage, or to "woohoo" (have sex - tastefully hidden from view) with 1-3 other sims, even before marriage. however, no babies can be made without trying as far as i know (but can be had out of wedlock), and abortions are impossible.
regarding babies - that aspirations thing fills up when you fulfill your sims' wants, and you will not find a "conceive a baby" want, but there is a "HAVE a baby" one. is it not a baby until birth?
when he/she is born this cutscene plays: youtube.com/watch?v=ULykWo0LSDc
i can't tell if the gem splits off (is created only then and there) or pops out of the mom's. :/
