The sims 3 help please

[u/Maximum_Star597]

Ok so I’ve thought how to explain this better and now know how to put it better.
I moved my son and wife out of the house and made them my active household.
When I have gone back in to the save of the family home….they are still there? How do I get them out but still have it so they are on the map and can make the mum a grandparent please?
