How do you change the gender of a Sim?

My sim on ';Sims 2'; had a baby boy, but I don't want a boy. Does anyone know how I can change it to a girl?How do you change the gender of a Sim?
Gender of the child is decided at birth. If you really want one gender and not the other, the only effective way to do it is to save just before the birth and keep replaying it till you get the gender you want. Say you got a boy first, exit without saving and go back into the lot at the save point and try again. It can be a bit of a fiddle. You can also change gender in SimPE but it's not 100% effective and can cause problems for the game.How do you change the gender of a Sim?
