When your baby gets born and the gender isn't the gender you had planned it to be you get a person from the family to hold (play, feed or sing) to the baby. You then delete the person holding the baby (be sure to save first) and you baby crib should reappear. the gender may change (you may have to try several times) (you delete the person holding the baby by using the "move_objects on" cheat) Good luck! P.S. don't delete the baby a few days after because it might not work and starts the three days all over again!
