If you guys are having troubles making babies, here's a helpful tip/trick. Once your couple is married make sure they're healthy, fed, and happy. The meters don't have to be full; just make sure their status says "happy" or "elated". As soon as they get married don't let them celebrate, make them try and make a baby immediately. If it says they're arguing then keep trying. More then likely they should make a baby. Remember this tip only works as soon as they get married.
