Choose Your Baby's Gender on "The Sims 3"
Confirm the Sim is pregnant before eating anything. There are two ways to determine if the Sim is pregnant. The first is children's music playing right after the Sims get done with WooHoo. If you did not hear the music, once your female Sim starts running to the bathroom with morning sickness, the pregnancy is confirmed.
Eat the three watermelons or apples, depending on which gender is desired, in succession.
