Knowing some of the ways Arthur's mind works I wouldn't be surprised if she becomes a Master in her career in double-quick time, and you have to drag her away from working. Peeps seem to take great delight in being cussed sometimes.

I generally make sure a female peep has completed successfully at least one work cycle (with use of the green glove to reinforce the 'lesson') before I have her try for a baby. That way she's likely to make a start on continuing her career after the baby starts to run around before I reopen the game.
In one case I had to leave for work in a few minutes, so had my new bride try for a baby as soon as she got married with no time for the usual training. When I got back home she was already on level 3, even after taking time out to have the baby.
