I see the sims can autonomously adopt pets but is there a way for them to autonomously adopt children? I have a gay couple and I want them to be able to adopt without me having to use the option of making them pregnant when they woohoo, especially my male sims. Let me know! thanks :lovestruc

Yes, NRaas StoryProgression can allow for autonomous adoption but there will be times when we would like not actively being played couples to adopt and how long it takes them to get around to doing so on their own could be not worth waiting for. NRaas MasterController has an Adopt Sim command that can be used to make that happen right away by player direction on actives or inactives.

what do I click on to activate this for inactives? I thought i must've skipped it or it wasn't an option.

To allow inactives to adopt autonomously (note this same setting applies to both adopting kids and pets):
NRaas > SP > Town (Household, Caste, Sim) Options > Pregnancy:Allow Adoption > True
(on sims for Sim/Household Options, City Hall or computer for Caste/Town Options)

To help increase (or decrease) the chances of this happening across the board, also subject to the sims' traits, on City Hall or an in-game computer,
NRaas > SP > General Options > Options:Pregnancy > Options:Adoption > Chance of Adoption > (is 30 by default, try increasing it)
NRaas > SP > General Options > Options:Pregnancy > Options:Adoption > Increased Chance of Adoption > (is 10 by default)
(SP Population add-on module required)
The first number measures the chances that someone in town will consider adopting every cycle of the manager, it doesn't mean there is a 30% chance that each individual sim will adopt, so don't be afraid to try something like 80 or 90 there. If the first try fails, the second number indicates the increased chance for the next cycle.

To just cause an inactive sim to adopt on the spot, that's MasterController.
NRaas > MC > (Sim) > Basic > Adopt
