This mod unlocks Suggest Having A Baby for same gender couples and emulates pregnancy and childbirth for them.
After using the interaction, there is a 50% chance of getting an excited pregnancy buff (as well as morning sickness) that progresses over three days' time.
Overtime, your Zoi will gradually gain temporary weight until 'childbirth' - which actually is just the Medical Birth screen popup.
Remember to have your 'pregnant' Zoi selected so you don't miss the popup! And don't forget to pick your partner! Your Zoi will 'give birth' and lose weight immediately after. You still have to pay for the Medical Birth.
