How do you make your sim have children on Sims 3?

Answer 1

On PC/Mac you get both sims to relax in the same double bed, as the male sims click on the female sim and click try for baby. Once you hear the rock a by baby it worked. You will be sure if your sim is fleeing nauseous. If your sim isn't a vampire make sure it doesn't eat any plasma before you get the pregnant moodlet otherwise you don't know if its pregnancy or just the plasma. 1 day after the try for baby if it worked you should get the pregnancy moodlet and some parenting related wishes. If you want a boy get the pregnant sim to eat about 4 apples before the 3rd trimester. If you want a girl have the pregnant sim eat 4 watermelons instead. To increase the chance at pregnancy have at least 1 of the parents have the fertility treatment reward. I personally find that if both sims have fertility treatment I get twins every time.
