How to have a Science Baby

You can have a baby with any friendly unrelated acquaintance. However, you can also opt to have a Science Baby 'as a single parent', and the DNA of said baby will be from your chosen sim, Their family tree will only list one parent.

You can also choose to have a Science Baby with another sim, or you can select the sim you want to have the baby with from a list of your acquaintances. You do not need to have a romantic connection with them in order to do this.

To have a Science Baby, simply click on the mobile icon at the bottom left of the screen (next to the calendar and sim profiles) and select the home icon.

There, you will see your options for having a Science Baby, both of which will cost you 1,200 simoleons. Once chosen, your sim will disappear and return momentarily with the baby, without the need to wait for the usual pregnancy and birthing times.
