About This Mod
Sims 4 added a new science baby feature that lets Simmers raise kids without having to get pregnant and give birth. Normally, these science babies show up on your doorstep once you complete the interaction. The Science Baby Tweak Mod lets you choose between instant delivery and causing a pregnancy. It’s a small adjustment, but it gives players the freedom to choose how they want to start their family.
