I wanted a 4 family household with 2 parents and 2 children 1 male, 1 female. I use insimenator mod quite often, which doesn't let you change gender. A baby's gender is random. The parents had a male child, I summoned a female townie and added her to the household. I set her parent family ties to the parents, but there is no option for sibling. I remember vaguely there was a way to do it in SimPE possibly with sim surgery, but I'm very rusty with that function. Is there a way to make an outsider a sim's sibling? Either with a game mod, or in simPE or insimenator or some cheat? Any input is appreciated.
