Do you have to have the Generation expansion pack? My sims have just had their third baby and he was working when the last one was born, but he didn't get any time off for at all. There is the hubby and wife, and his parents, who are self-employed, so they wouldn't get any time off, as far as a job goes.
But he didn't get any.
They don't need the money, they have over 2 million dollars, so no one has to work, but it is a project game, so he has to work for that reason.
