I also think it would be cool if they implemented an option to have a Science Baby via pregnancy! I guess I can understand why the team chose a more open-ended option to not include pregnancies at all. The omission of a pregnancy does cover a larger variety of player’s stories. Oh well, a missed opportunity.
I think when I utilize this feature, I’ll create a holiday on the calendar for the baby’s arrival and play through a baby shower event to ensure the new addition’s arrival feels just as significant as any other. Luckily we have those options at least!
