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.
