I found out how to travel through the game faster than how it goes, if that made any sense. what i mean is that, instead of waiting like 4 hours to try and make a baby again, or if your waiting for the parents to age, all you have to do is go to your clock at the bottom of the screen (PC) and I think it's at the top for mac, and change the time, maybe put it 4 hours ahead or 8 hours ahead or even a day, but make sure that they have enough food to last them for that long. Hope I helped, let me know if you have problems with this.
