How long do pregnancies last? Goblins 15 days, vampires 25, BB and Venomina 7, everyone else 20. Birth is the next day, the day they get pregnant counts as day 1. BB and Venomina lay eggs you can harvest rather than having kids.How long till the kids show up?
Some first pregnancies are driven by story events and can vary from that. Vixinatrix lays eggs which do not (yet) hatch; same for ED's first pregnancy.
