I don't see why have the option to have kids if you don't get to rise them in anyway. I not one of the peeps who wanted the sex & pregnancy update, I was down for the Personality & the Jobs update.
but I feel if you going to have an update to make sex more meaningful than the act of having a child & being able to rise them into adulthood would be the most fulling thing too those who want to roll play a happily ever after with their in-game wife.
Cause other wise just rollover the sex mini game over into the personality update as a way to enhance interactability with the women at that point.
