Thanks,
I knew there was a limit to eight, and have changed some traits in the edit town, traits not given when a sim ages up. Used the modify as one kid aged up to teen and he went from fit to seriously overweight.
That is basically what I want to do, create some families that have children already at older stages, teen, YA's and move them to a town to increase population. What I am wondering is, when I create the family, am I limited to just the couple in the start of the game, or can I add more.
Such as create a family of four, mom, dad and two kids; one child, one teen. Put them in a nice home, save them to library and then tranfer them to MF.
