I have been playing for a while with this family and am now playing with the second generation. It's 2 families in 1 house, one pregnant sim and one baby (making six). I wanted one of the families to have another kid, but the try for baby icon is greyed out and if I try to click it it says that the household is too full. I had this when the first generation was still living there as well and I had them move out. I've tried resetting sims, copying the household to library, deleting them from the game and putting them back in, moving, clearing the cache, but nothing works! Anyone have an idea how I can fix this?
