The second setting should be applied to the prospective father/other parent as well. NRaas > SP > Sim Options > Pregnancy: Allow Participation > True NRaas > SP > Sim Options > Pregnancy: Allow Can Be Pregnant > True So on your own teens, and only those you want to be pregnant, set this: By default, StoryProgression blocks members of the Teen caste (automatic, meaning all teens are members) from becoming pregnant or being the other parent.
