The red Pries hair lost in just one generation? What a disappointment! Still, Giselais a lovely infant/toddler and she does have pointy ears. I should think we're all thinking what you're thinking about Rogelio, lol.
I've definitely had some unexpected genetic results. Cassandra Calixte has 2 parents with black or jet-black hair but she has mid-brown. Maybe she was swapped at birth with one of yours?
Is Top-Notch-Infant purely down to the Loved and Well-Cared-For buffs? That's pretty easy with singles or twins but I can imagine it's a nightmare with triplets! I find, as Watcher, I can't leave them or their needs tank even if I wait until they're asleep. I just always write off the Infant stage insofar as getting anything else done.
I haven't tried for a baby shower because I don't enjoy them irl, lol. I'll have a look on my game and see if they're available.
Sigh, yes, not even a single redhead out of that bunch. But Gisela has violet eyes with pointy ears and she's lovely. *sniffle, sniffle
Top-Notch Infant is, afaik, unrelated to milestones. I'd never aged infants up early before, but now i shall never do 5 full days of infanthood again.
Regarding infants/toddlers at home:
If she leaves Andoni and/or Marcos home with the kids, the kids' needs don't recover. If they were exhausted when she leaves, they'll be exhausted when she returns.
However, if she takes Andoni & Marcos with her, the infants' needs recover.
That's why the grown-ups can go out when the kids go to bed, staying out until their Energy recovers 100%. It works that way with toddlers, too.
I'm not a fan of the Sims 4 Baby Shower either actualy. The gold-medal bassinet is only usable for 24 hrs at most. It's more the principle, haha.
