Your sims will dive under the covers and giggle and have their fun, with fireworks. You may be able to skip some of those but hey, who doesn't like a little foreplay? They'll also give a little boost to your sims' relationships, which can be helpful if the 'try for baby' option doesn't show up when you first relax. With one sim selected in live mode, click on the other sim and choose cuddle, then kiss, then make out, then try for baby. They'll need to be in love to be able to try for baby (or woohoo). The easiest way to get pregnant is to have a male and female sim relax on a bed. You'll also need to pay for bottles (which come out of your food budget) and perhaps hire a nanny, so having at least 5000 simoleons per baby is advised. This means you'll need to have some simoleons saved up to pay for a crib and changing table, a separate area in which to put the nursery, and enough simoleons ready to convert that nursery into a new bedroom for the child once they grow up. Try to make sure your sims are ready for the new arrival.
