I'm having the same problem. None of my sims are producing either. However I haven't had any other problems with this mod, it works great. I am new to this mod, and still trying to figure out a lot of the features. I have enable story progression on in options, as well as aging. I have plenty of empty starter homes with cribs. I think the problem might be that random famiilies keep moving into them. I keep evicting them, but i'll go back into my game and play for a night or two, and wham, they are full again. Is there any way that I can stop new random families or single sims from moving into my starter houses? I don't think the problems I am having are due to awesome mod at all, but just due to my ignorance. lol
Thank you for the help.
