My legacy currently has 7, which wasn't intentional. Hello twins..twice. I'll probably have to move the eldest out once she reaches young adult, and maybe take the younger set with her to make room for my heir and their husband/children, which I haven't decided between my older set of twins yet. I don't mind the challenge of 7 of them, but I find I don't tend to leave my home lot often since someone always has something they need to do, so since we can't queue up a bunch of things and leave.. I tend to stay home. :(
