I can't see a problem. She appears to have planned for middle aged lack of energy and her impending mortality by hiring a nanny and ensuring that the child has a strong and stable network.
Hopefully she will still be alive when Pia hits 20ish. After that, it looks like there's enough money (and a father) to get Pia into her mid twenties.
After that, a parent is desirable, but not essential.
The bar has changed for the middle aged woman. Back in the day, you hit 50, cut your hair short, wore a headscarf and spent your life in slippers, waiting for grandchildren and death.
Now we have decades of work and promotion ahead of us, better nutrition and well-being advice, HRT, botox and plastic kneecaps. If we're expected to use advanced medical techniques look and work like young woman (and have to suck it up; I was looking forward to the slippers) why not use advanced medical techniques for our own benefit?
