Does Anyone Know Of A Mod That Prolongs Labor?

I make my sim's pregnancies last 9 days with MCCC and you can stop your sim from delivering by deleting the bassinet when it's placed or keeping your sim from going to it, which can be done without MCCC. My pet peeve with TS4 is the lack of morning sickness, as it seems to have almost disappeared with updates to the game. I had sims in the past who would get a little sick and others who would have morning sickness throughout their pregnancy.
