There is nothing hard or confusing to do, in fact, the game has it built in the system but no one has noticed. Here it is: When your person is sick, wait until their action bar tells what is making them sick then give them the red glove five times in a row. It may seem a little cruel but it works and is free. When you want to have a baby but your people don't want too, simply drag them on to each other (like you normally would) and when they argue, give them to red gloves each. Keep doing so until you have a baby. I have found this out with experience.
