To check if two particular sims can be pregnant and impregnate (participate), on the sims themselves check NRaas > SP > Sim Options > and thenĪllow Participation Caste (probably blank, but could be restricted here to other teens only for example)ĭisallow Participation Caste (could be blank, but could also include Elders or Adults if wanted)ĭisallow Can Be Pregnant Caste (could be blank but same as above) The Town Settings on the left would apply to everyone else who doesn't have heavier weighted settings applied to them on the right.
So it doesn't matter what the Town settings are, it matters what the Caste, Household, and Sim settings are for the teen sims. But settings on the right will trump, that is override, settings on the left.
In SP, the settings flow like this: Town > Lot > Caste > Household > Sim.
