Who said that the Mom carrying the baby isn't making any money??!!

Correct me if I'm wrong, but I do believe that the women get paid whether they are "working on [their] career" or not (I've checked my "$" button for details). Meaning that both the men and women are paid a daily income, even if they never work a single cycle in the whole game. (See this thread for more information on how peeps get paid.)

Those men and women who are set to "work on career" are working on advancements in their career. And are paid accordingly, on top of their daily income when they work a cycle.

Let's keep in mind that this game isn't about who makes more money (everyone's salary is agreed upon when we adopt or marry), or who works harder (that's what the gloves are for).

This IS, however, a game about family. There is nothing wrong with a stay-at-home/work-at-home mother/wife (or father/husband)! There isn't anything wrong with letting one of the two peeps get all of the advancements, while the other doesn't advance at all. Whatever combination works for you. It's your game. Make it fun!
