Could you tell how this works more specifically? What did the child inherited from mom? Do they inherit traits? What is the ratio between mom's abilities and that of the child's?
They inherited her beauty, dex, int, academy, and tech at 100+,90,90,80+,70+ respectively. This a fully trained future chancellor and the nanny is the Stormchild since she can boast an impressive 124 int and 100 discipline. Discipline though doesn't transfer and is the key stat for sending out successful children. If you don't send them out, Aria can pop fully prepared professor straight out of the womb. You don't need discipline for academy job.
If you plan on sending them out, the highest influence is the performer which needs the Starlet trait or 80+ performance. Performance isn't inheritable, kids will start at ~20. Either train it or F5 the kid to get the trait. With the automation mod, I get a small window that preview traits so I F5 shamelessly to get what I want. The best money earner is the scientist which needs Science 80 and discipline 50. All paths are further boosted by discipline 80 and workaholic which I do F5 too(it's a damn pain and a half to train otherwise). Discipline is annoying to get that high since you can't make the kids housemaid last I checked. You can make them guards though, so a competent Captain would automate that.
It's a long term investment that is easy to setup and automate but with dubious returns. Sure you can have a stable of kids out in the world earning $ and influence that are untaxed and invulnerable to all modifiers. But by the time you're at that point, your workshop is churning cash, and the Zapin fields --> ration --> orphanage --> influence pipeline is roaring through.
However, if you wanna RP your little own royal family, as I said Aria and the Stormchild deliver womb-ready professors. So you can staff the academy with your progeny.
